URGENT!! WILL GIVE BRAINLIEST

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%

astronomers is your final answer! : )
