Dividing a 2-digit number by 1 1/3

1. Select a 2-digit number.
2. Multiply by 3.
3. Divide by 4.

   Example:

1. The 2-digit number chosen to divide by 1 1/3 is 47.
2. Multiply by 3: 3 x 47 = 120 + 21 = 141
3. Divide by 4: 141/4 = 35 1/4
4. So 47 divided by 1 1/3 = 35 1/4.

   See the pattern?

1. The 2-digit number chosen to divide by 1 1/3 is 82.
2. Multiply by 3: 3 x 82 = 246
3. Divide by 4: 246/4 = 61 1/2
4. So 82 divided by 1 1/3 = 61 1/2.

With this pattern you will be able to give answers quickly, but most importantly, your answers will be exact. If a calculator user divides by 1.3, the answer will NOT be correct.
