Multiplying a 2-digit number by 1 5/6

1. Select a 2-digit number.
2. Multiply by 11.
3. Divide the result by 6.

   Example:

1. The 2-digit number chosen to multiply by 1 5/6 is 34.
2. Multiply by 11: 11 x 34 = 374
   (Add the digits left to right.
   The last digit is 4.
   The next digit is 4 + 3 = 7.
   The first digit is 3.)
3. Divide by 6: 374/6 = 62 2/6
4. So 34 x 1 5/6 = 62 1/3.

   See the pattern?

1. If the 2-digit number chosen to multiply by 1 5/6 is 62:
2. Multiply by 11: 11 x 62 = 682
3. Divide by 6: 682/6 = 113 4/6
4. So 62 x 1 5/6 = 113 2/3.

To produce these products promptly, practice multiplying by 11.
