Total number of girls are 72.
Let total boys are 8x and total girls are 9x.
According to the question,
Since, number of boys are 8x. So,
So, the number of boys are 64.
6 = x + 2/3
We're simply just trying to get "x" isolated.
So, we must subtract 2/3 from both sides.
6 - 2/3 = x
Simplify.
Turn 6 into an improper fraction.
6 is now 18/3 :)
So, our new problem looks like this :
18/3 - 2/3 = x
Simplify.
16/3 = x
Turn 16/3 into a mixed fraction.
How many times does 3 go into 16? 5 times! :)
So, we do this :
3 × 5 = 15
16 - 15 = 1
So, x = 5 1/3
