Chapter 12.8, Problem 36S

To determine

To evaluate: the given expression.

Answer to Problem 36S

The required solution is 41

Explanation of Solution

Given: $\frac{21+43+59}{3}$

Calculation:

Consider the expression

  $\frac{21+43+59}{3}$

The objective is to find the value of the expression.

To find the value of the expression first add the terms in the numerator and the divide the numerator by the denominator term.

The value of the numerator term is

  $\begin{array}{l}21+43+59=64+59\\ =123\end{array}$

Now check whether the numerator is divisible by $3$ and write the answer.

  $\begin{array}{l}\frac{21+43+59}{3}=\frac{123}{3}\\ =41\end{array}$

Therefore,

  $\frac{21+43+59}{3}=41$

Conclusion:

Therefore,the required solution is 41
