Multiplying a 2-digit number by 1 1/9

1. Select a 2-digit number.
2. Add a zero to the number.
3. Divide the result by 9.

   Example:

1. The 2-digit number chosen to multiply by 1 1/9 is 32.
2. Add zero: 320
3. Divide by 9: 320/9 = 35 5/9
4. So 32 x 1 1/9 = 35 5/9.

   See the pattern?

1. If the 2-digit number chosen to multiply by 1 1/9 is 74:
2. Add zero: 740
3. Divide by 9: 740/9 = 82 2/9
4. So 74 x 1 1/9 = 82 2/9.
