Question

One half of the sum of numbers x and y is ??

Answer 1

Hint: In this question, we need to form the expression as the question says. Half a number means dividing a number by two, so the expression that shows half of a number 'x' is x2 , ( i.e).divide a number by two) . Half is also defined as one part of something dividing into two equal parts.

Complete step-by-step answer:
Given, sum of numbers $(x)$ and $(y)$
Sum of $(x) $ and $(y) $ is$(x + y)$
Now in the question given that we need to form the expression of one half of the sum of numbers $(x)$ and $(y)$, (i.e) . One half of${x + y}$
One half is nothing but dividing the number by half.
$(\dfrac{1}{2} \times \left( x + y \right)) $
By multiplying,
We get,
$(\dfrac{x + y}{2})$
One half of sum of numbers $(x)$ and $(y)$ is $(\dfrac{x + y}{2})$

Note: : We need to know that ``one half’’ is the same as ``a half ``.It is an irreducible fraction . It is numerically written as $(\dfrac{1}{2}) $. Similarly ‘’one third’’ is written as $(\dfrac{1}{3}) $ ,”Two-third” as $(\dfrac{2}{3}) $ and so on. In other words, one half is defined as if the numerator goes down into the denominator by two times.
