first you have to get the number on the right 40 to equal 100 so do 40x2=80- +40x1.5= 100

Then do the same thing to the first number 8 so 8x2=16+8x1.5=20

then you have 20/100 right so then that number over 100 is the percent that you get ^-^ 20%
Divide 8 by 40 and you get 0.2 or 2 tenths which equals to 20%.

Use a calculator, it always helps.
