Many calculators will deal with percentages directly. If yours doesn't, you may need to convert the percentage to a decimal fraction. Since "%" means the same thing as "/100", you know that 68% is the same as 68/100, or 0.68 (sixty-eight hundredths).

Using your multiplication skills, you can do this in your head with a simple transformation of the problem:

  0.68×150 = 68×1.50 . . . . multiply one factor by 100; divide the other factor by 100

  = 68×1 +68×0.50 . . . . . . use the distributive property

  = 68 + 68/2 . . . . . . . . . . . recognize multiplying by 0.5 is dividing by 2

  = 68 +34 = 70 +32 . . . . . rearrange the addition to simplify, if you like

  = 102
