Answer 1

Answer:

Step-by-step explanation:

Given,

CLASS A

Total number of students: 20

Total number of girls: 14

CLASS B

Total number of students: 25

Total number of girls: 15

To Find,

1) Percentage of girls in each class:

Percentage = $\frac{Part}{Whole}$ × $100$

                    = $\frac{Number Of Girls}{Total Number Of Students}$ × $100$

CLASS A

Percentage = $\frac{14}{20}$ × $100$

                    = $70$ %

CLASS B

Percentage = $\frac{15}{25}$ × $100$

                    = $60$ %

Hence, Class A has 70% Girls while Class B has 60% Girls.

2) Which class has more girls ?

By comparing the above data we can find that Class B has more girls in class. (Class A = 14, Class B = 15)

3) Which class has the greater percentage of girls ?

By comparing the above data we can find that Class A has a higher percentage of girls in class. (Class A = 70%, Class B = 60%)
