The total area given is 36 cm.^{2} .
The red part should be thrice the yellow .
The denominators are common .
Just add all the daily numbers up .
Is cut into 4 parts once and then into three parts .
Please have a look at ry1 .
This time multiplication. You can check the result by finding the product.
Put A = 1 000 000 000 and try how approximate the result is .
999 999/1 000 001 = 0.999998000001999998000001999998 and
1 000 001/999 999 = 1.000002000002000002000002000002 .
1/A = 5 means A = 1/5. One way may be to evaluate 1/(1/5 - 1 ) = 1/(-4/5)= ?
The second possibility is to reduce the fraction by A and get : (1/A)/(1-1/A) = 5/(1-5) .
For A=1/1 000 000 = 0.000001 we have 1/(1-A) = 1.000001000001000001000001000001 and 1+A = 1.000001 .
Half of the class is 18 .
1/(1-A) + 1/(1+A) = (1+A+1-A)/(1-AxA)
1/2 is a proper fraction while 1/2 + 1/2 is equivalent to unity and improper .
How many 3/9 is there in 27/9 ?
1/5 = 14/70 and 3/7 = 30/70 .
IV is wrong + ... .
C-1 has none .
Have please a look at ry1 .
