Question

4.
Find:
(a) 1/4 of 20 =​

Answer 1

Given:

$\frac{1}{4}$ of $20$

$\frac{1}{4}\times 20$

$=5$

Hence $5$ is the answer

Answer 2

Given,

Expression: $\frac{1}{4}$ of 20.

To find,

Value of given expression.

Solution,

To find the value of a "fraction of a whole number", the fraction is simply multiplied by the given number, and then the obtained expression is further simplified. For example, if we need to find $\frac{x}{y}$ of N, where N is a whole number. Then it will be,

$\frac{x}{y} \times N$.

So, for the given expression,

$\frac{1}{4}$ of 20

= $\frac{1}{4} \times 20$

Now, $\frac{1}{4} \times 20$ can be simplified as,

$\frac{1}{4} \times 20=\frac{20}{4}$

= 5.

⇒ $\frac{1}{4}$ of 20 = 5.

Therefore, the value of 1/4 of 20 will be 5.
