In a group of 60 students, 20%are girls. How many are boys?

Firlakuza [10]

Answer: About 12 of those 60 students are boys.

To find the percent, you'll convert 20% to a decimal.

20 / 100 = 0.2

Then, multiply 60 by 0.2

0.2 × 20 = 12

That's one way, another way is:

Convert 20% to a fraction.

20% = 1/5

Then multiply 60 by 1/5.

60 × 1/5 = 60/5

Lastly, divide 60 by 5

60 / 5 = 12.

Hence, 12 is the answer.
