    First you select one cube the fraction is 5/12 after you select the other the cube you already used one so the fraction is 4/12 5-1=4

    First you divide (What you want)/(what you've got) So 5/12 Then multiply it by (What you want)/(what you've got) but remember that one ball has gone 4/11 Then multiply both numbers 5/12.4/11

    so you start out with 15 cubes but you take one (red and put it in your pocket then you pick again with 14 cubes and take one again (red)
