Dividing a 2-digit number by 1 1/9

steps

1. Select a 2-digit number.
2. Multiply by 9.
3. Move the decimal point one place to the left.

Example:

1. The 2-digit number chosen to divide by 1 1/9 is 24.
2. Multiply by 9: 9 × 24 = 180 + 36 = 216
3. Move the decimal point one place to the left: 21.6
4. So 24 divided by 1 1/9 = 21.6.

See the pattern?

1. The 2-digit number chosen to divide by 1 1/9 is 91.
2. Multiply by 9: 9 × 91 = 819
3. Move the decimal point one place to the left: 81.9
4. So 91 divided by 1 1/9 = 81.9.
