FIFTH GRADE /MULTIPLICATION / TEST 1.3

MATHEMATICS IS EASY. PROVIDED THAT ONE WORKS ENOUGH.
ENOUGH IS SKILL DEPENDENT, HAVE TO FIND "ENOUGH" FOR YOUR SIZE.

SOME OF OUR QUESTIONS ARE REALLY HARD, FOR THOSE THAT ARE SKILLED IN MATH.
SKIP THEM IN CASE NOT FOR YOU.

IF YOU DESIRE SO, WE CAN DISCUSS HARD/INTERESTING QUESTIONS IN OUR FORUM.

 Method(s) of MULTIPLICATION of INTEGERS is (are)

   ♦ 
METHOD(s) of DETERMINING the RESULT of
   ♦ COUNTING FORWARD from ZERO by BLOCKS containing so many NATURAL NUMBERS called a MULTIPLICAND

   ♦ by an AMOUNT of ANOTHER GIVEN INTEGER NAMED again a MULTIPLICAND.

    Ref.-1
 * There are diff. methods all doing the same .
1. The old KWH meters consider 3 parameters: Voltage, current and time. Consumption is calculated based on these parameters. The product of these 3 factors gives the consumption.
How many Wattsxhour is the consumption of an household that used a current of 10 A for 100 hours under a voltage of 220 V. ?

!


a) 220 000
b) 22 000
c) 440 000
d) 280 000
The unit are the ones normally used and compatible with each other. Just multiply the 3 numbers given .
2. What amount should be paid by the consumer of the previous question if 1 kW x hour of energy costs $0.1 ?

a) $90
b) $150
c) $220
d) $22
10x100x220 = 220 000 W x hour = 220 kW x hour.
!
3. The multiplication table given just above refers to base 13. What do we obtain for Q6xQ in case we use the given table ?

a) 991
b) 1639
c) 1366
d) 889
Qx6=51 , write 1 and carry 5 .
4. Using the multiplication table for base 13 given above, which is the correct way of evaluating the product of Q6 x 1Q ?

!


a) III
b) II
c) IV
d) I
We know the first product (multiplication with ones' of the second factor) is 991.
The second product is the result of multiplication by 1 but in reality it is a 13 that means Q6 should only be shifted.
Be careful about carry as you add .
5. Which number corresponds to 1821 of base 13 in base 10 ?

a) 2367
b) 2987
c) 3576
d) 4376
13x13x13 + 8x13x13 + 2x13 + 1 = ? .
y
6. The multiplication below has mixed coding; the factors are coded base 13 (joker stands for 0, then the digits up to 9, and then J, Q and K) and the product base 10.
Which choice is the decoded form of this multiplication ?

!
In case of need for tips get the cursor on "y" or for help click at "ry1/2" .
RY1 RY2



a) 11x6 + 13x11x11 = 1639
b) 12x6 + 13x10x11 = 1639
c) 12x6 + 13x11x10 = 1639
d) 10x7 + 13x11x12 = 1639


Play cards are used except for 10, joker is 0, J corresponds to 10 of base 10 etc. Have a look at ry1 .

7. What is wrong with the statement "If a multiplication operation has 5 operands, it is plausible to put the smallest operand at the top."?

a) The order of operands do not play a role as we do multiplication.
b) This is a proper claim.
c) The greatest operand must be top.
d) Multiplication is a binary operation, a multiplication does not have 5 operands.
4 basic operations are all binary operations.
It is possible to write terms like axbxc, a+b+c, ... etc. but they are evaluated via consecutive evaluations of each binary operation.
8. The polar bear has an approximate density that is equal to the density of the ice. Both are floating. The total volume of the bear and the seen part of ice is about 1 m3.
What should the total volume of ice+bear be (m3) ?

!


a) 11
b) 10
c) 12
d) 9
The part unseen must be 9 times the part seen .
9. 1, 4, 9, 16, 25, 36, ... and 55, 50, 45, 40, 35, 30, ... are two different patterns that may have a common element after a while. Which number will be obtained if the sum of elements of each pattern seperately obtained till this common element and then these sums are multiplied ?

a) 17350
b) 15400
c) 14700
d) 12650


25 is the first common element.
10. In Turkey nominal voltage used by households is 220 V but this may drop to 180 V in prime times due to high consumption. KWH meter may only measure the current and assume constant voltage.
What is the excess amount of money paid by the household of question 1 that consumed 220 kW x hour under 200 V which is assumed to be 220 V ?

a) $100
b) $20
c) $2
d) $1
The households real consumption is 200 kW x hour and it should have paid $20 .
11. In which choice base 10 form of the multiplication seen in question 12 (the next question) is given ?

a) 141x12 = 1692
b) 141x24 = 3384
c) 149x12 = 1788
d) 149x24 = 3576
Q6 in base 13 is 11x13+6 = 149 in base 10.
y
12. Below in the figure is a litle bit changed form question 6. The second factor is also 2-digit. All seen numbers are base 13 coded. The first contributor, the first summand, to/of the product seems to have a 6 at ones' but from question 6 we know it should be a 9 in base 10.
How is this situation to be explained ?


In case of need for tips get the cursor on "y" or for help click at "ry1/2".

RY1 RY2



a) 11x6=6 is right, the answer to 1st Q. is wrong.
b) 6 there is wrong, should be a conversion error
c) 6 may be 9 in a different coding
d) multiplication can only be done in base 10
The correct number that should be just below the multiplication line is given in ry1. Have please a look at ry1 .
13. Recently some 800 km3 ice volume melts yearly and mixes into sea water. How many m3 is this volume ?

a) 800 000 000
b) 80 000 000 000
c) 800 000 000 000
d) 8 000 000 000 000
To convert km3 to m3 we need to multiply it by 1 000 000 000.
14. If floating ice melts in pure water the total volume of ice+water does not change. Sea water is not pure and if floating ice in sea water melts a volume increase of 1/40 of ice volume happens. Under the assumption that all melting ice of previous question is floating ice, the volume of sea increases by 20 000 000 000 m3.
How many m3 will be the total increase of oceans volume in the next 10 years under these assumptions ?

a) 200 000 000 000
b) 20 000 000 000
c) 2 000 000 000 000
d) 100 000 000 000
Just multiplication by 10. The question aims to teach the physical properties of ice-sea water.
15. The radius r of the Earth is 6 000 000 m. What will (m2) then be the surface area of the Earth if it is to be calculated via A = 12.5 x r x r ?

a) 450 000 000 000 000
b) 45 000 000 000
c) 450 000 000 000
d) 4 500 000 000 000
12.5 x 36 000 000 000 000 = 50 x 9 000 000 000 000 = ?
16. The area of seas is about 3/4 ths of the area of the Earth and may be approximated as 336 000 000 000 000 m2. What will be the excess amount of volume (m3) then produced if sea height increases by 1 mm. ?

a) 3 360 000 000
b) 33 600 000 000 000
c) 3 360 000 000 000
d) 336 000 000 000
Just drop 3 "0"s from the given number to make m. out of mm.
17. What is then the relation between M (the excess volume due to melting floating ice in 10 years) and W ( the volume that increases the sea level by 1 mm.) ?

a) M = W
b) M > W
c) M < W
d) M = W

Note: All ice melting is not floating and the sea level is claimed to increase
by 1 mm. in a year.
Under these assumptions sea level increases by 1 mm. in about 20 years .
y
18. Our computers do differentiate 2 levels due to the transistors being main elements and work binary. The numbers we enter are converted to base two, operations are done and then the results reconverted to base 10 via software. We see ten the form we understand on our screens.
A computer having an interesting virus can not make the conversion to base 10 and converts to base 13 instead and uses/places a "." for each character that is not among the normal digits base 10 uses.
What are we supposed to see at the screen if we want this infected computer to make the operation 243x27 ?
