For both of them you just make them into fraction. For #2 and then you simplify it 36. ÷12 3 -----. =. -------- 120. ÷12 10 After this you want to change the fraction to a percentage.Percentage are out of 100
so you simply will multiply by 10 to the top and bottom 3. 30 ----. * 10 =. -----. = 30% 10. 100
The answer is 30%
For number #3 you simply put 63 over 240 63 ----- 240 21 ---- 80 is that answer because it can't be simplified after that
