Question

The ratio of boys to girls at a rock concert was about 7 to 6. if there were 1,092 boys at the rock concert, how many girls were there?

Answer 1

Let The Number Of Boys At The Rock Concert Be 7x.
Let The Number Of Girls At The Rock Concert Be 6x.
There Were 1,092 Boys At The Rock Concert.
7x=1,092
x=1,092÷7
x=156
6x=156×6
6x=936
If There Were 1,092 Boys At The Rock Concert,There Were 936 Girls.

Answer 2

let y be the one part in the ratio,
so you get 7y : 6y.
using the information given, calculate what y is. just divide 1092 by 7, which y= 156.
since there's 6 y(s) , just multiply 156 by 6,
so there r 936 girls in the concert
