Dividing a 2-digit number by 40

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

1. The 2-digit number chosen to divide by 40 is 21.
2. Multiply by 5: 5 × 21 = 105.
3. Divide the result by 2: 105/2 = 52.5.
4. Move the decimal point two places to the left: 0.525.
5. So 21 divided by 40 = 0.525.

   See the pattern?

1. The 2-digit number chosen to divide by 40 is 73.
2. Multiply by 5: 5 × 73 = 350 + 15 = 365.
3. Divide the result by 2: 365/2 = 182.5.
4. Move the decimal point two places to the left: 1.825.
5. So 73 divided by 40 = 1.825.
