What number should be multiply $\frac{12}{4}$ to get $\frac{20}{3}$

Answer:_______________

What number should be multiply $\frac{7}{4}$ to get $\frac{15}{5}$

Answer: $\frac{12}{7}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{15}{5}$

Given number x Required number = $\frac{15}{5}$

$\frac{7}{4}$ x Required number = $\frac{15}{5}$

Required number = $\frac{15}{5}$ x $\frac{4}{7}$

= $\frac{12}{7}$

What number should be multiply $\frac{9}{4}$ to get $\frac{12}{2}$

Answer: $\frac{8}{3}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{12}{2}$

Given number x Required number = $\frac{12}{2}$

$\frac{9}{4}$ x Required number = $\frac{12}{2}$

Required number = $\frac{12}{2}$ x $\frac{4}{9}$

= $\frac{8}{3}$

What number should be multiply $\frac{5}{2}$ to get $\frac{16}{4}$

Answer: $\frac{8}{5}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{16}{4}$

Given number x Required number = $\frac{16}{4}$

$\frac{5}{2}$ x Required number = $\frac{16}{4}$

Required number = $\frac{16}{4}$ x $\frac{2}{5}$

= $\frac{8}{5}$

What number should be multiply $\frac{7}{4}$ to get $\frac{16}{4}$

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

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{16}{4}$

Given number x Required number = $\frac{16}{4}$

$\frac{7}{4}$ x Required number = $\frac{16}{4}$

Required number = $\frac{16}{4}$ x $\frac{4}{7}$

= $\frac{16}{7}$

What number should be multiply $\frac{8}{3}$ to get $\frac{17}{4}$

Answer: $\frac{51}{32}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{17}{4}$

Given number x Required number = $\frac{17}{4}$

$\frac{8}{3}$ x Required number = $\frac{17}{4}$

Required number = $\frac{17}{4}$ x $\frac{3}{8}$

= $\frac{51}{32}$

What number should be multiply $\frac{9}{2}$ to get $\frac{10}{2}$

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

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{10}{2}$

Given number x Required number = $\frac{10}{2}$

$\frac{9}{2}$ x Required number = $\frac{10}{2}$

Required number = $\frac{10}{2}$ x $\frac{2}{9}$

= $\frac{10}{9}$

What number should be multiply $\frac{3}{4}$ to get $\frac{15}{7}$

Answer: $\frac{20}{7}$

SOLUTION 1 :

Soln :

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

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

$\frac{3}{4}$ x Required number = $\frac{15}{7}$

Required number = $\frac{15}{7}$ x $\frac{4}{3}$

= $\frac{20}{7}$

What number should be multiply $\frac{1}{3}$ to get $\frac{20}{5}$

Answer: $\frac{12}{1}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{20}{5}$

Given number x Required number = $\frac{20}{5}$

$\frac{1}{3}$ x Required number = $\frac{20}{5}$

Required number = $\frac{20}{5}$ x $\frac{3}{1}$

= $\frac{12}{1}$

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 $\frac{4}{9}$

= $\frac{64}{45}$

10)

What number should be multiply $\frac{12}{4}$ to get $\frac{20}{3}$

Answer: $\frac{20}{9}$

SOLUTION 1 :

Soln :

The product of two rational numbers = $\frac{20}{3}$

Given number x Required number = $\frac{20}{3}$

$\frac{12}{4}$ x Required number = $\frac{20}{3}$

Required number = $\frac{20}{3}$ x $\frac{4}{12}$

= $\frac{20}{9}$
