Hi there.

5.25 - 3.75 (I converted the fractions to decimals to make things a little more simple, but I'll convert them back to fractions.)

First, subtract .25 from 5.25 and 3.75. This allows the process to be easier to break down without making mistakes.

Now, subtract .50 from 5 and 3.50.
We now have 4.50 - 3.00; simple enough from here, right?

4.50 - 3.00 = 1.50, but if we convert it back, we have 1 and 1/2.

Your answer is 1 and 1/2 or 1.50

I hope this helps!
