wlad13 [49]

The whole number of \dfrac{1}{4} is \boxed{0.25}.

Further explanation:

Always use the PEDMAS rule to solve the grouping of multiplication, addition, subtraction and division.

Here, P is parenthesis, E is exponents, M is multiplication, D is division, A is addition and S is subtraction.

Given:

The number is \dfrac{1}{4}.

Explanation:

The whole numbers is the series of numbers that starts from zero.

The natural numbers are those numbers that start from one.

The place values are only natural numbers.

The base ten systems represent the position of a place value.

The given number is \dfrac{1}{4}.

Consider the number \dfrac{1}{4} as \text{A}.

A = \dfrac{1}{4}

Divide 1 by 4 to obtain the whole of \dfrac{1}{4}.

\begin{aligned}\text{A}&= \frac{1}{4}\\&= 0.25\\\end{aligned}

The decimal expansion of \dfrac{1}{4} is 0.25.

The whole number of \dfrac{1}{4} is \boxed{0.25}.
