We may have some formulas to remember and use.
Even and odd has lost sense. mod 3 and mod 9 will not work any more due to division.
Subtraction is always inverse of addition and may be used as a check.
Every time we divide by 10 and specify a coefficient, a whole lot, an infinite amount in between are skipped.
This is because points have no dimension.
It should be between 0.1666... and 0.125 .
There are conversion formulas among different bases, a number in coded base 2 may be converted to a number in base 10 .
22/7 is almost π which is 3.1416...
1/2 + 5/2 = 3 So the sum should be around 6.14
5.5 / 9 since 1/6 = 3/18 = 3/2 x 1/9. We write it as 11/18
Gitche Manito, the mighty, The creator of the nations,
Looked upon them with compassion, With paternal love and pity;
Looked upon their wrath and wrangling But as quarrels among children,
But as feuds and fights of children!
Over them he stretched his right hand,
To subdue their stubborn natures, To allay their thirst and fever,
By the shadow of his right hand; Spake to them with voice majestic
As the sound of far-off waters, Falling into deep abysses,
Warning, chiding, spake in this wise:--
"O my children! my poor children!
We are trying to drive you to the concept of denseness that you will later learn. We want you to be curious.
Remember this is not a valid check anymore. Just sum all digits and omit any mutiple of 3 at both sides of the equation.
Remember this is not a valid check anymore. Just sum all digits and omit any mutiple of 9 at both sides of the equation.
First came 560 of them . Then another 75 .
The basics must be known by some people in the society and we need to know how to operate machines, must have sense of it.
(7/9+8/9+1)/3 is desired and 1 + 7/9 = 16/9
Listen to the words of wisdom,Listen to the words of warning,
From the lips of the Great Spirit,
From the Master of Life, who made you!
"I have given you lands to hunt in,
I have given you streams to fish in,
I have given you bear and bison,I have given you roe and reindeer,
I have given you brant and beaver,
Filled the marshes full of wild-fowl,
Filled the rivers full of fishes: Why then are you not contented?
Why then will you hunt each other? "I am weary of your quarrels,
I is trivial.
II. 11/16 + 2/16 after reductions.
III can not be correct.
1+3+4-7 + 27/41 + 47/123 + 36/82 = (81 + 47 + 54)/123 .
372 x 4/3 = 496 & 4/3 x 45 = 60 .
I is obviously around 5.9
37/9 is approximately 4 and ... which means II is around 7.5 - 8.
427/76 is is around 425/75 = 17/3 and all together around 8.5
These are mixed numbers, calculate first the integer part. Do not be afraid, go on and see.
3+4+5=12
3/5 + 6/7 = 51/35 which means total fractional part is around 92/35 (little bit less than 3)
4/15 + 3/10 + 1/5 = 23 / 30 .
11/12 + 30/36 = 21/12 with common den. 60
Two fractions a/b and c/d are equivalent (equal) only if the product of the numerator (a) of the first fraction and the denominator (d) of the
other fraction is equal to the product of the denominator (b) of the first fraction and the numerator (c) of the other fraction.
Tree fractions that satisfy the given conditions: 17/15 , 17/16 and 1 .
Set the whole number part aside and find first 17/15 + 17/16 = 527/240 = 2 47/240 .
So the total whole number of the sum is 3 and the proper fractional part is 47/240. These should be divided by 3
Do not disregard the whole part.
Do not get demoralized, it is simple; your self-confidence solves it.
The answer may be a or b.
43/117 is approx. 45/125=9/25=0.36 and 13/11=1.18 less then 1.2 anyway
Just count the elements .
Find first the sum of first 4. Common denominator is 36. Sum is (36+18+9+4)/36 = 67/36
67/36 + 1/25 = (67x25 + 36)/900 = 1711/900
