Question

Which one of the following is correct?
The sum of :
Statement a: A decimal and a whole number is always a whole number.

Statement b: Two decimals is always a whole number.

Statement c: Two whole numbers will always be a whole number.

• A. Only a is true
• B. Only b is true
• C. Only c is true
• D. All are true

Answer 1

The correct option is C

Only c is true

Sum of two whole numbers will always be a whole number.
For example: 5 + 7 = 12.
Sum of two decimals will not be a whole number always. For e.g. 2.6 + 1.2= 3.8

It can be a whole number sometimes, for example 2.5 + 1.5 = 4, which is a whole number.

Sum of one decimal and a whole number will always be a decimal. For example 1.5 + 2 = 3.5, which is a decimal.
