What number should be multiply $\frac{1}{3}$ to get $\frac{10}{7}$

Answer:_______________

What number should be multiply $\frac{12}{3}$ to get $\frac{14}{3}$

Answer: $\frac{7}{6}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{14}{3}$

Given number x Required number = $\frac{14}{3}$

$\frac{12}{3}$ x Required number = $\frac{14}{3}$

Required number = $\frac{14}{3}$ x $\frac{3}{12}$

= $\frac{7}{6}$

What number should be multiply $\frac{7}{4}$ to get $\frac{20}{8}$

Answer: $\frac{10}{7}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{20}{8}$

Given number x Required number = $\frac{20}{8}$

$\frac{7}{4}$ x Required number = $\frac{20}{8}$

Required number = $\frac{20}{8}$ x $\frac{4}{7}$

= $\frac{10}{7}$

What number should be multiply $\frac{10}{4}$ to get $\frac{15}{7}$

Answer: $\frac{6}{7}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{15}{7}$

Given number x Required number = $\frac{15}{7}$

$\frac{10}{4}$ x Required number = $\frac{15}{7}$

Required number = $\frac{15}{7}$ x $\frac{4}{10}$

= $\frac{6}{7}$

What number should be multiply $\frac{12}{3}$ to get $\frac{14}{8}$

Answer: $\frac{7}{16}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{14}{8}$

Given number x Required number = $\frac{14}{8}$

$\frac{12}{3}$ x Required number = $\frac{14}{8}$

Required number = $\frac{14}{8}$ x $\frac{3}{12}$

= $\frac{7}{16}$

What number should be multiply $\frac{7}{2}$ to get $\frac{11}{7}$

Answer: $\frac{22}{49}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{11}{7}$

Given number x Required number = $\frac{11}{7}$

$\frac{7}{2}$ x Required number = $\frac{11}{7}$

Required number = $\frac{11}{7}$ x $\frac{2}{7}$

= $\frac{22}{49}$

What number should be multiply $\frac{9}{4}$ to get $\frac{16}{5}$

Answer: $\frac{64}{45}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{16}{5}$

Given number x Required number = $\frac{16}{5}$

$\frac{9}{4}$ x Required number = $\frac{16}{5}$

Required number = $\frac{16}{5}$ x $\frac{4}{9}$

= $\frac{64}{45}$

What number should be multiply $\frac{6}{3}$ to get $\frac{16}{7}$

Answer: $\frac{8}{7}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{16}{7}$

Given number x Required number = $\frac{16}{7}$

$\frac{6}{3}$ x Required number = $\frac{16}{7}$

Required number = $\frac{16}{7}$ x $\frac{3}{6}$

= $\frac{8}{7}$

What number should be multiply $\frac{7}{4}$ to get $\frac{18}{5}$

Answer: $\frac{72}{35}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{18}{5}$

Given number x Required number = $\frac{18}{5}$

$\frac{7}{4}$ x Required number = $\frac{18}{5}$

Required number = $\frac{18}{5}$ x $\frac{4}{7}$

= $\frac{72}{35}$

What number should be multiply $\frac{5}{4}$ to get $\frac{10}{4}$

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

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{10}{4}$

Given number x Required number = $\frac{10}{4}$

$\frac{5}{4}$ x Required number = $\frac{10}{4}$

Required number = $\frac{10}{4}$ x $\frac{4}{5}$

= $\frac{2}{1}$

10)

What number should be multiply $\frac{1}{3}$ to get $\frac{10}{7}$

Answer: $\frac{30}{7}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{10}{7}$

Given number x Required number = $\frac{10}{7}$

$\frac{1}{3}$ x Required number = $\frac{10}{7}$

Required number = $\frac{10}{7}$ x $\frac{3}{1}$

= $\frac{30}{7}$
