Answer: $\frac{35}{18}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{5}{3}$

One rational number = $\frac{6}{7}$

Given number x required number = $\frac{5}{3}$

$\frac{6}{7}$ x required number = $\frac{5}{3}$

Required number = $\frac{5}{3}$ x $\frac{7}{6}$

= $\frac{35}{18}$

The product of two rational numbers is $\frac{8}{5.}$ If one of the numbers is $\frac{2}{4}$ , find the other rational number.

Answer: $\frac{16}{5}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{8}{5}$

One rational number = $\frac{2}{4}$

Given number x required number = $\frac{8}{5}$

$\frac{2}{4}$ x required number = $\frac{8}{5}$

Required number = $\frac{8}{5}$ x $\frac{4}{2}$

= $\frac{16}{5}$

The product of two rational numbers is $\frac{6}{4.}$ If one of the numbers is $\frac{5}{7}$ , find the other rational number.

Answer: $\frac{21}{10}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{6}{4}$

One rational number = $\frac{5}{7}$

Given number x required number = $\frac{6}{4}$

$\frac{5}{7}$ x required number = $\frac{6}{4}$

Required number = $\frac{6}{4}$ x $\frac{7}{5}$

= $\frac{21}{10}$

The product of two rational numbers is $\frac{6}{4.}$ If one of the numbers is $\frac{2}{6}$ , find the other rational number.

Answer: $\frac{9}{2}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{6}{4}$

One rational number = $\frac{2}{6}$

Given number x required number = $\frac{6}{4}$

$\frac{2}{6}$ x required number = $\frac{6}{4}$

Required number = $\frac{6}{4}$ x $\frac{6}{2}$

= $\frac{9}{2}$

The product of two rational numbers is $\frac{5}{5.}$ If one of the numbers is $\frac{4}{7}$ , find the other rational number.

Answer: $\frac{7}{4}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{5}{5}$

One rational number = $\frac{4}{7}$

Given number x required number = $\frac{5}{5}$

$\frac{4}{7}$ x required number = $\frac{5}{5}$

Required number = $\frac{5}{5}$ x $\frac{7}{4}$

= $\frac{7}{4}$

The product of two rational numbers is $\frac{3}{5.}$ If one of the numbers is $\frac{6}{6}$ , find the other rational number.

Answer: $\frac{3}{5}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{3}{5}$

One rational number = $\frac{6}{6}$

Given number x required number = $\frac{3}{5}$

$\frac{6}{6}$ x required number = $\frac{3}{5}$

Required number = $\frac{3}{5}$ x $\frac{6}{6}$

= $\frac{3}{5}$

The product of two rational numbers is $\frac{3}{4.}$ If one of the numbers is $\frac{6}{6}$ , find the other rational number.

Answer: $\frac{3}{4}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{3}{4}$

One rational number = $\frac{6}{6}$

Given number x required number = $\frac{3}{4}$

$\frac{6}{6}$ x required number = $\frac{3}{4}$

Required number = $\frac{3}{4}$ x $\frac{6}{6}$

= $\frac{3}{4}$

The product of two rational numbers is $\frac{4}{5.}$ If one of the numbers is $\frac{4}{5}$ , find the other rational number.

Answer: $\frac{1}{1}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{4}{5}$

One rational number = $\frac{4}{5}$

Given number x required number = $\frac{4}{5}$

$\frac{4}{5}$ x required number = $\frac{4}{5}$

Required number = $\frac{4}{5}$ x $\frac{5}{4}$

= $\frac{1}{1}$

The product of two rational numbers is $\frac{2}{3.}$ If one of the numbers is $\frac{5}{7}$ , find the other rational number.

Answer: $\frac{14}{15}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{2}{3}$

One rational number = $\frac{5}{7}$

Given number x required number = $\frac{2}{3}$

$\frac{5}{7}$ x required number = $\frac{2}{3}$

Required number = $\frac{2}{3}$ x $\frac{7}{5}$

= $\frac{14}{15}$
