Question

The product of two fraction is 63/5.if one of the fraction is 15/7, find the other

Answer 1

Answer:

Given:

product of two fractions = 63/5

one of fractions = 15/7

Proof:

assume that other number = x

15/7 [x] = 63/5

x = [63/5] [7/15]

x = 441/75

Verification:

[ 15/7 ] [ 441/75 ]  = 63/5

63/5 = 63/5.

Answer 2

$let \: \: \: \: other \: \: \: \: fraction \: \: \: \: be \: \: \: \: x \\ \\ x \times \frac{15}{7} = \frac{63}{5} \\ \\ x = \frac{63 \times 7}{15 \times 5} \\ \\ x = \frac{21 \times 7}{5 \times 5} \\ \\ x = \frac{147}{25}$
