Question

If the product of two fractions is 7, of which one fraction is 5/13.Find the others fraction​

Answer 1

Step-by-step explanation:

The other is 91/5.

So 7 is the product of two fractions, a and b.

ab=7

Let a=5/13.

5b/13=7

13/5×5b/13=7×13/5

b=91/5

Proof:

5/13×91/5

5÷5=1

1/13×91/1

91÷13=7

1/1×7/1=7
