Answer 2

Given: $3:11:: 7:?$

We have to find the missing number.

• As we know that a proportion is an equation in which two ratios are set equal to each other.

We are solving in the following way:

We have,

$3:11:: 7:?$

Let assume the missing number is$x$.

Then,

$3:11:: 7:x$

Now from the above concept, we can write:

$=>\frac{3}{11} =\frac{7}{x} \\\\=>3\times x=7\times 11\\\\=>3x=77$

Now we will separate the variables on one side and the constant on another side.

$=>x=\frac{77}{3}$

Hence, the missing number will be$\frac{77}{3}$.
