Question

________ makes one whole.
A) One half
B) Two halves
C) Three halves

Answer 1

Hint: A whole number means a number without any fraction part. So, to find what makes one whole, we will check each option and see if we get a whole number or a fraction. Also, one whole means real number 1. So, we will be finding how many halves make 1 whole number.

Complete step by step solution:
In this question, we are asked what makes one whole number.
First of all, let us see what one whole means.
Whole numbers are a part of a number system which includes all the positive integers from 0 to infinity. So, we can say that all the whole numbers are real numbers but not all real numbers are whole numbers.
A Whole number is a number without any fraction. So, one whole number means real number 1.
Let us check all the options.
Option A: One half
One half in fraction form means ${\displaystyle \frac{1}{2}}$. Hence, it is not a whole number. So, we can say that option A is not the correct answer.
Option B: Two Halves
Two halves in fraction form means ${\displaystyle \frac{1}{2}}$ and ${\displaystyle \frac{1}{2}}$. When we add them, we get
$\Rightarrow {\displaystyle \frac{1}{2}}+{\displaystyle \frac{1}{2}}={\displaystyle \frac{2}{2}}=1$
Here, 1 is a whole number and without any fraction. Hence, we can say that two halves make 1 whole.
Hence, option (B) is the correct answer.

Note:
We have seen what whole numbers and fractions are. Now, there is a third type of number system that is mixed numbers.
A mixed number is a number which contains a part whole number and a part fraction.
For Example: $1{\displaystyle \frac{1}{2}}$
