Question

In a class of 30 students, 13 of them are boys.

What percentage of the class are girls?
Give your answer to 1 decimal place.

Answer 1

56.7%

Explanation:

Total number of students = 30

Number of boys in the class = 13

Number of girls in the class = 30 - 13 = 17

Now we have to find the percent of girls of the class

Therefore

`\frac{\text{Number of girls}}{\text{Total students}} *100`

`=(17)/(30)*100=56.67\%`

`56.67\implies56.7\%`

Hence, girls are 56.7% of the class.

Answer 2

13/30 x100=43.3333…

Convert to one decimal place = 43.3
