Question

What percent of $80$ is $20$ ?

Answer 1

Hint: In order to find out the required percentage, we first need to divide $20$ by $80$ . Doing this, we get the corresponding fraction. Multiplying it with $100$ , we get the required percentage. The mathematical form will be $\dfrac{20}{80}\times 100\%=25\%$ .

Complete step by step answer:
Fractions and percentages are different ways to express portions or parts of a substance. Percentages are nothing but fractions, but expressed out of $100$ . The term “percent” consists of two words, “per” and “cent” where per means “out of” and cent means “hundred”. Thus, it clearly makes sense what percentage or percent means. Percentage is a scale to express what portion of a substance or number is a given substance or number. The scale has the lowest value of zero percent, which means none and the upper value as hundred percent which means full.
To find out percent, we usually divide the portion by the parent number. For example, if we want to find out what percent is $2$ of $3$ , we need to divide $2$ by $3$ . Doing this, we get the fraction. Multiplying it with $100$ , we get the required percentage.
For the given problem, we need to find out what percent of $80$ is $20$ . The parent number here is $80$ and the portion is $20$ . We divide $20$ by $80$ . After that, we multiply by $100$ . Thus,
$\dfrac{20}{80}\times 100\%=25\%$

Therefore, we can conclude that $20$ is $25\%$ of $80$.

Note: Percentage calculations are pretty easy, but even these calculations are prone to mistakes. For example, we can mistakenly divide $80$ by $20$ and get a completely wrong answer. We should also make sure whether we put the percent sign or not, as not putting it will not be understandable.
