Answer 3

i think it is A

Answer 4

80% of 160 is 128
85% of 120 is 102

So 128 - 102 = 26
Obviously there are 26 girls more in 4th grade with long hair...
Fair enough? :)

thank you

Answer 6

Do you know how to get 80% of 160?

Answer 7

no i do not

Answer 8

Ok, you know that there are always 1-100%
So ANY number you are asked, just divide it but 100 first, and you will get value for 1%
And then multiply it by number you need, in this case 80...

160/100*80 = 128
120/100*85 = 102

If you need 5%
160/100*5
If you need 0.5%
160/100*0.5

Ok? :)
