Question

What number is 0.5% of 8?
(a) 0.08
(b) 0.04
(c) 0.01
(d) None of these

Answer 1

Hint: In this given problem, we are finding the value of 0.5% of 8. Now, 0.5% says $\dfrac{0.5}{100}$in the simplification. Hence, we have our solution as, $\dfrac{0.5}{100}\times 8$. Simplifying this value, we will get our needed solution.

Complete step by step solution:
According to the problem, we are trying to find the value of 0.5% of 8.
Now, talking about the percentages, we have, to find the percentage of a number when it is in decimal form, you just need to multiply the decimal number by 100. For example, to convert 0.5 to a percentage, 0.5 x 100 = 25%. In the case of involving a fraction, if the given number is in fractional form, first convert it to a decimal value and multiply by 100.
Here, we have to find 0.5% of 8.
That tells us that, we have to calculate the value of, $\dfrac{0.5}{100}$ multiplied with the given number.
Thus, we have, 0.5% of 8 = $\dfrac{0.5}{100}\times 8$
Trying simplifying the numerator, we get, $0.5\times 8=4$
Then, our fraction becomes, $\dfrac{4}{100}$ .
Simplifying, will give us the result, $\dfrac{4}{100}=0.04$.

So, the correct answer is “Option b”.

Note: In the given problem, we have tried to use the properties of percentages. Considering them in mind, Percentages have no dimension. Hence it is called a dimensionless number. If we say, 50% of a number, then it means 50 percent of its whole. Percentages can also be represented in decimal or fraction form, such as 0.6%, 0.25%, etc.
