Answer 2

Given: $3:28::5:?$

We have to find the missing value.

• 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,

$3:28::5:?$

Let assume the missing number be$x$.

Then,

$3:28::5:x$

Now, from the above concept we can write:

$=>\frac{3}{28} =\frac{5}{x} \\\\=>3\times x=5\times 28\\\\=>3x=140\\\\=>x=\frac{140}{3}$

Solving the above further we get,

The value of $x$is$\frac{140}{3}$.

Hence, we get the missing number is$\frac{140}{3}$.
