The given question is the avg of 4 fractions is 1/2 three fractions are 0.02,0.01 & 1.5.find the 4th fraction?

An average of four fractions are given but only three components are there, we. have to find the fourth fraction.

The average of a fraction is defined by dividing the sum of the fractions by the total number of fractions.

The given fractions are 0.02,0.01 and 1.5 and let x be the fourth fraction

The sum of the fractions will be

$0.02 + 0.01 + 1.5 + x = 1.53 + x$

The average is given as

$\frac{1.53 + x}{4} = \frac{1}{2}$

On cross multiplying the values, we get,

$(1.53 + x) = \frac{4}{2}$

on further proceedings we get,

$1.53 + x = 2$

The constant on the left will move on to right with a change in the sign

$2 - 1.53 = x \\ x = 0.47$

Therefore, the value of the fourth fraction is 0.47.
