Dividing a 2-digit number by 1 3/4

1. Select a 2-digit number.
2. Multiply by 4.
3. Divide the product by 7.

   Example:

1. The 2-digit number chosen to divide by 1 3/4 is 34.
2. Multiply by 4: 4 x 34 = 136
3. Divide the product by 7: 137/6 = 19 3/7
   (If you use a calculator, you will get a long, inexact decimal number.)
4. So 34 divided by 1 3/4 = 19 3/7.

   See the pattern?

1. The 2-digit number chosen to divide by 1 3/4 is 56.
2. Multiply by 4: 4 x 56 = 224
3. Divide the product by 7: 224/7 = 32
4. So 56 divided by 1 3/4 = 32.

Notice that numbers divisible by 7 will produce whole-number quotients. For numbers not divisible by 7, your calculator will give you long decimal results that are not exact.
