   Dividing a 2-digit number by 37 1/2

  1. Select a 2-digit number.
  2. Multiply by 8.
  3. Divide the product by 3.
  4. Move the decimal point two places to the left.

   Example:

  1. The 2-digit number chosen to divide by 37 1/2 is 32.
  2. Multiply by 8: 8 x 32 = 240 + 16 = 256
  3. Divide by 3: 256/3 = 85 1/3
  4. Move the decimal point two places to the left: .85 1/3
  5. So 32 divided by 37 1/2 = .85 1/3.

   See the pattern?

  1. The 2-digit number chosen to divide by 37 1/2 is 51.
  2. Multiply by 8: 8 x 51 = 408
  3. Divide by 3: 408/3 = 136
  4. Move the decimal point two places to the left: 1.36
  5. So 51 divided by 37 1/2 = 1.36.
