Question

In a class of 50 students, 40% are girls. Find the number of girls.​

Answer 1

Answer: There are 20 girls

Explanation:

• 100% is the same as your original or total number → in this case, 100% is 50 students

• The first step is to work out 10%

→ Since 10% is the same as 100% divided by 10, we divide our original number (50) by 10.

50 ÷ 10 = 5

So, now we know that 10% of 50 is 5

• To calculate what 40% of 50 would be, we just multiply 10% by 4

5 x 4 is 20

Therefore, 40% of 50 students is 20.
