Carol noticed that 7/10 of the children playing soccer were girls. Which statement could be correct?

A. There were 28 girls and 12 boys playing soccer.

28 : x% = 40 (the total number of children) : 100%

40x = 28 * 100

40x = 2800

x = 2800 / 40

x = 70%

There were 70% of girls in the class.

70 / 100 = 0.7

7 / 10 = 0.7

This is why A is the correct answer.
