Question

the local chess club has 60 member. 24 of them are younger than twenty. what percent of members of the chess club are younger than 20

Answer 1

You can first write it as a fraction. 24 out of the 60 members are younger than twenty.

24/60

Simplify by dividing the numerator and denominator by the GCF, 12:

2/5

Percentages are parts of 100, so we want to get 100 in the denominator to find the percentage. 100 / 5 = 20, multiply numerator and denominator by 20:

40/100

This is 40 parts of 100 or 40%.

So 40% of the members of the chess club are younger than 20.

Answer 2

The local chess club has 60 members and 24 of the members are younger than 20. What percent of members are younger than 20?

The fraction
`(24)/(60)` represents the 24 members that are younger than 20 out of all the members in the club.

To find out what percent of members are younger than 20, we can turn
`(24)/(60)` into a percent.

We can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 24 and 60 using 12.

24 ÷ 12 = 2

60 ÷ 12 = 5

Now, we have our reduced fraction which is
`(2)/(5)`.

2 ÷ 5 = 0.4

0.4 × 100 = 40%

Therefore, 40% of the chess club members were under 20.
