in a given classroom the number of girls is 10 greater than number of boys if the ratio of the number of girls to the number of

Xelga [282]

Answer:

a) 35, b) 25, c) 60

Step-by-step explanation:

The number of girls is 10 more than the number of boys, so it's a good thing to choose a variable to represent the number of boys.

Number of boys: b

Number of girls: b + 10

Ratio of girls:boys is 7:5, so

$\frac{b+10}{b}=\frac{7}{5}$

"Cross multiply" to get

$7b=5(b+10)\\7b=5b+50\\2b=50\\b=25$

There are 25 boys. There are 10 more girls, so the number of girls is 35, and the total number of students is 60.

That's a packed classroom!
