Answer: 1/4 OR 1/8
Step-by-step explanation:
the first coin can be heads which has a 1/2 chance of happening and the other coin also has a chance to get tails which is 1/2
if you add the 1/2 and the other 1/2 you can get 1/4 OR 1/8
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%
