Dividing A 2-digit Number By 1 2/7

Dividing a 2-digit number by 1 2/7

  1. Multiply the number by 7.
  2. Divide by 9.

 

   Example:
  1. If the 2-digit number chosen to divide by 1 2/7 is 32:
  2. Multiply by 7: 7 × 32 = 210 + 14 = 224
  3. Divide by 9: 224/9 = 24 8/9
  4. So 32 / 1 2/7 = 24 8/9.

   See the pattern?

  1. If the number to be divided by 1 2/7 is 61:
  2. Multiply by 7: 7 × 61 = 427
  3. Divide by 9: 427/9 = 47 4/9
