Answer: $\frac{49}{6}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{7}{3}$

One rational number = $\frac{2}{7}$

Given number x required number = $\frac{7}{3}$

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

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

= $\frac{49}{6}$

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

Answer: $\frac{49}{25}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{7}{5}$

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

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

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

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

= $\frac{49}{25}$

The product of two rational numbers is $\frac{6}{5.}$ If one of the numbers is $\frac{2}{5}$ , find the other rational number.

Answer: $\frac{3}{1}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{6}{5}$

One rational number = $\frac{2}{5}$

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

$\frac{2}{5}$ x required number = $\frac{6}{5}$

Required number = $\frac{6}{5}$ x $\frac{5}{2}$

= $\frac{3}{1}$

The product of two rational numbers is $\frac{3}{4.}$ If one of the numbers is $\frac{5}{6}$ , find the other rational number.

Answer: $\frac{9}{10}$

SOLUTION 1 :

Soln :

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

One rational number = $\frac{5}{6}$

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

$\frac{5}{6}$ x required number = $\frac{3}{4}$

Required number = $\frac{3}{4}$ x $\frac{6}{5}$

= $\frac{9}{10}$

The product of two rational numbers is $\frac{3}{4.}$ If one of the numbers is $\frac{2}{4}$ , find the other rational number.

Answer: $\frac{3}{2}$

SOLUTION 1 :

Soln :

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

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

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

$\frac{2}{4}$ x required number = $\frac{3}{4}$

Required number = $\frac{3}{4}$ x $\frac{4}{2}$

= $\frac{3}{2}$

The product of two rational numbers is $\frac{8}{5.}$ If one of the numbers is $\frac{6}{5}$ , find the other rational number.

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

SOLUTION 1 :

Soln :

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

One rational number = $\frac{6}{5}$

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

$\frac{6}{5}$ x required number = $\frac{8}{5}$

Required number = $\frac{8}{5}$ x $\frac{5}{6}$

= $\frac{4}{3}$

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

Answer: $\frac{2}{1}$

SOLUTION 1 :

Soln :

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

One rational number = $\frac{3}{6}$

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

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

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

= $\frac{2}{1}$

The product of two rational numbers is $\frac{2}{3.}$ If one of the numbers is $\frac{6}{7}$ , find the other rational number.

Answer: $\frac{7}{9}$

SOLUTION 1 :

Soln :

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

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

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

$\frac{6}{7}$ x required number = $\frac{2}{3}$

Required number = $\frac{2}{3}$ x $\frac{7}{6}$

= $\frac{7}{9}$

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

Answer: $\frac{3}{2}$

SOLUTION 1 :

Soln :

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

One rational number = $\frac{3}{6}$

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

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

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

= $\frac{3}{2}$

10)

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

Answer: $\frac{25}{18}$

SOLUTION 1 :

Soln :

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

One rational number = $\frac{6}{5}$

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

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

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

= $\frac{25}{18}$
