Question

if 4/5=12/?, then ?=​

Answer 1

Given: $4/5=12/?$

We have to find the missing value.

We are solving in the following way:

We have,

$4/5=12/?$

Let assume the missing value be$x$.

Then,

$=>\frac{4}{5} =\frac{12}{x}$

For this, we will separate the variables on one side and the constant on another side.

$=>4\times x=12\times5$

Multiplying the above terms:

$=>4x=60\\\\=>x=\frac{60}{4}$

Solving the above expression further we get,

$=>x=15$

Hence, the missing number will be$15$.
