The phrase "per hour" gives us a clue that we are going to divide. In this problem, we can replace the word "per" with a division sign; therefore, we will have the portion of his workout, 
, divided by hours, 
:
Remember that when we divide fractions, we can simply multiply by the reciprocal of the denominator to solve.
Therefore:
Andrew can complete 
of his workout per hour.

In order to solve this problem, we need to start at 
on the number line.
Next, we have 
which means we need to move 
places to the right on the number line. When we have an addition sign 
we move to the right because that is towards the positive side of the number line. When we have a subtraction sign 
we move to the left because that is towards the negative side of the number line.
