Question

7/8%of 80
please send with explanation​

Answer 1

Step-by-step explanation:

Let x = 7/8 of 80.

Let y = 1/4 of 90.

So the quotient is x/y.

7/8 of 80 means 7*80/8 = 7*10 = 70 so x = 70.

1/4 of 90 means 90/4 which is 45/2 which is 22.5

so x/y is 70/22.5 which is 140/45.

let’s simplify further.

140 = 7*2*5*2 = 2^2 *5*7

45 = 3^2 * 5

so there is a 5 in common which can be cancelled from top and bottom.

2^2*7 = 28.

3^2 = 9

so x/y = 28/9.

Therefore if 7/8 of 80 is divided by 1/4 of 90 the quotient is 28/9. or 3 19 .

Hope this helps.

Answer 2

Step-by-step explanation:

7/8/100×80

7/8×10×8 (80 100 0 cut and 10 came in multiplication) (8 to 8 in denominator and numerator cancelled out)
