Dividing a 2-digit number by 1 2/3

1. Select a 2-digit number.
2. Multiply by 6 (or by 2 and 3).
3. Move the decimal point one place to the left.

   Example:

1. The 2-digit number chosen to divide by 1 2/3 is 78.
2. Multiply by 3: 3 x 78 = 210 + 24 = 234
3. Multiply by 2: 2 x 234 = 468
4. Move the decimal point one place to the left: 46.8
5. So 78 divided by 1 2/3 = 46.8.

   See the pattern?

1. The 2-digit number chosen to divide by 1 2/3 is 32.
2. Multiply by 3: 3 x 32 = 96
3. Multiply by 2: 2 x 96 = 180 + 12 = 192
4. Move the decimal point one place to the left: 19.2
5. So 32 divided by 1 2/3 = 19.2.

Practice multiplying from left to right and you will become adept at mentally dividing a number by 1 2/3.
