Question

The $0.5\%$ of $490$ is what number?

Answer 1

Hint: Percentage means “per cent” which means “out of 100 parts”. For solving this question, we first assume that 0.5% of 490 is $x$ . And then, to find the value of $x$ , we first convert the percentage 0.5 into a fraction and multiply it with 490 to find the answer.

Complete step by step answer:
As per the definition of percentage, when we express something in the form of percentage, for example 60%, what we mean is 60 parts for something in its 100 parts. To convert a percentage into a fraction, we have to divide it by 100.To convert 0.5% into a fraction,
$\dfrac{{0.5}}{{100}} = 0.005$
Now for finding the value of $x$ , we multiply the above value with 490.Therefore, we get:
$0.005 \times 490 = 2.45$

Hence, we can write that 0.5% of 490 is 2.455.

Note: To solve the above question, one must be familiar with the concept of percentage. When we convert a value, say a decimal or a fraction, into a percentage value, we divide it with 100. A percentage is just a number or a fraction multiplied with 100, so it has no units.
