Answer:
1. 5 fewer boys
2. 7 more girls
3. there was an increase
4. 3% change
Step-by-step explanation:
I think that is the answer to get it i multiplied the percentage with the boys so for example 25× 20%= 5
then you subtract 25-5=20 boys
same thing for the girls 28×25%=7
28+7=35
for the third question you add the previous girls and boys
25+28=53
and the after
35+20= 55
so there was an increase
the last question you subtract before from after
55-53=2
and then you divide 2 from 55
2/55= which is .03
you make it into a percentage by moving the decimal two places to the right and you get 3%
