Start with 3 1/4. 3 whole units, and 1/4 (one quarter of a unit) added. How many quarter units are in 3 whole units? Each unit contains 4 quarters, or 4/4. So 3 units contains 12quarters. 12 quarters plus the one added quarter give you 13 quarters, or 13/4. Do this division, 13 divided by 4, and you will have your decimal.

Another way to think of it is that in the answer you are already going to have the 3 in place, because the fractional remainder (the 1/4) is not greater than one. Do the division 1/4, or 1 divided by 4, and add that decimal to the 3. 1/4 is equal to .25, so the answer will be 3.25.
