what percentage of the class are girls ?
give your answer to 1 decimal place

Answer 1

56.7 %

Explanation:

In a total of 30 students, if there are 13 boys then there are 17 girls. If we want to find the percentage of our focus, it can be done by the following:

`\displaystyle{\text{Percentage of what we focus} = \frac{\text{Focus}}{\text{Total}} * 100}`

So if we want to find the percentage for girls then our focus is 17 girls and total is 30 students:

`\displaystyle{(17)/(30)* 100}\\\\\displaystyle{=(17)/(3)* 10}\\\\\displaystyle{=(170)/(3)}\\\\\displaystyle{=56.7 \, \%}`

Therefore, around 56.7% are girls.
