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? :)

Ok, you know that there are always 1100% 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? :)
