Percentages | Math | Broomfield School
Q&A Practice Quiz

A percentage is a way to show what percent of something there is. For example, 10%
means that there are 10 parts out of $80.




1. Calculate 10% of $80.

Let 10% of $80 = X

10/100 * £80 = X

Answer: X = $8




2. What is 40% of 120?

40% of 120

= (40/100) × 120

Answer = 48




3. If 16% of 40% of a number is 8, then find the number.

Let X be the required number.

Therefore, as per the given question,

(16/100) × (40/100) × X = 8

So, X = (8 × 100 × 100) / (16 × 40)

Answer = 125



4. What percentage of 2/7 is 1/35 ?

Let X% of 2/7 is 1/35.
∴ [(2/7) / 100] × X = 1/35

⇒ X = (1/35) × (7/2) × 100 Answer = 10%
