Question

Identify the whole and fractional part for the number $4.5$?

• A. Whole part $=5$
  Fractional Part $=4$
• B. Whole part $=4$
  Fractional Part $=5$
• C. Whole part $=4$
  Fractional Part $=.5$
• D. Whole part $=4.0$
  Fractional Part $=0.5$

Answer 1

The correct option is B Whole part $=4$

Fractional Part $=5$
The given number is $4.5$

The left of the decimal point is known as the whole number part and the right of the decimal point is known as the fractional part.

Let's understand this concept using pizzas.
4 complete pizzas are there that represents the whole number 4, and half pizza (1/2 = 0.5) of a whole represents a fractional part 0.5.
So, 4.5 pizza is shown above

$\text{Hence, Whole part}=4$,
$\text{Fractional Part}=5$.
