In this video you will learn how to subtract fractions from whole numbers.

The shortcut involves borrowing a one from the whole number, and then rewriting the whole number as a fraction using the value of the denominator.

Let's look at one example.

5 -1/4

Step 1. 5-1 =4

Step 2. Rewrite the one as 4/4

Step 3. Subtract 4/4-1/4 =3/4

Step 4. Solution Add step 1 and step 3 ( 4 + 3/4 = 4 3/4)

This technique even works for mixed fractions.

The video works several examples, and gives more detailed directions.
