Follow the Following Steps:

  1. Select a 2-digit number.
  2. Multiply by 8.
  3. Divide the product by 5.
  4. Move the decimal point 3 places to the left.

   Example:1

  1. The 2-digit number chosen to divide by 625 is 65.
  2. Multiply by 8: 8 × 65 = 480 + 40 = 520
  3. Divide by 5: 520/5 = 104
  4. Move the decimal point 3 places to the left: .104
  5. So 65 divided by 625 = .104.
   Example:2
  1. The 2-digit number chosen to divide by 625 is 32.
  2. Multiply by 8: 8 × 32 = 240 + 16 = 256
  3. Divide by 5: 256/5 = 51.2
  4. Move the decimal point 3 places to the left: .0512
  5. So 32 divided by 625 = .0512.
