Question

In a class of 42 students, the number of boys is ⅖ of the girls. Find the number of boys and the number of girls in the class.​

Answer 1

Answer:

girls is 42

Step-by-step explanation:

(1) B+G=42

(2) B=25×G

Replacing B by (2) we get:

25×G+G=125×G=42

Turning 125 into a non-mixed fraction:

75×G=42→ multiply by 5, divide by 7:

G=42×57=6×7×57=30

B=25×30=25×5×6=12

And these add up to 42.
