Answer:
117 girls
Explanation:
If 64% are boys, the percentage of girls can be found by subtracting this amount from 100:
100 - 64 = 36
So 36% of 325 are girls.
To find the amount from a percentage use the following formula:
Original amount *

Now plug these values in:
= 117
So there are 117 girls in the 325 children.
Hope this helps!
