Question

The product of two fractions is 88. If one of the fraction is 3 1/7 . Find the other

Answer 1

Answer:

19.87

31/7*19.87=88

31/7*x=88

88*7/31=x

19.87=x

Answer 2

Let the other no. be x

$\sf\tt{3 \frac{1}{7} \times x = 88}$

$\sf\to \: \: {(3 \times 7 + 1)x = 616}$

$\sf\to \: \: {(21 + 1)x = 616}$

$\sf\to \: \: {22x = 616}$

$\sf\to \: \: {x =\frac{616}{22}}$

$\sf{\purple{\to\:\:{x = \frac{22}{1}}}}$

Therefore, the other no. is 22/1 or 22.
