Dividing a 2- or 3-digit number by 16 2/3

1. Select a 2-digit number. (Choose larger numbers when you feel sure about the method.)
2. Multiply by 6 (or by 3 and then 2).
3. Move the decimal point two places to the left.

   Example:

1. The 2-digit number chosen to divide by 16 2/3 is 72.
2. Multiply by 3: 3 x 72 = 216
3. Multiply by 2: 2 x 216 = 432
4. Move the decimal point 2 places to the left: 4.32
5. So 72 divided by 16 2/3 = 4.32.

   See the pattern?

1. The 2-digit number chosen to divide by 16 2/3 is 212.
2. Multiply by 3: 3 x 212 = 636
3. Multiply by 2: 2 x 636 = 1200 + 72 = 1272
4. Move the decimal point 2 places to the left: 12.72
5. So 212 divided by 16 2/3 = 12.72.

Practice multiplying by 3, then by 2, and you will be able to do these problems quickly.
