Rob planned on spending three hours reading in preparation for his literature exam. If he ends up spending only three-quarters of this time reading, and he reads a page every fifteen minutes, how many pages did he read in this time?
1 hour is 60 minutes so 3 hours is 3*60 = 
<gadget id="calculator">3*60</gadget>
<output>180</output>
180 minutes.
Three-quarters of 180 minutes is (3/4)*180 = 
<gadget id="calculator">(3/4)*180</gadget>
<output>135</output>
135 minutes.
He spends 15 minutes on 1 page so he will spend 135 minutes on 135/15 = 
<gadget id="calculator">135/15</gadget>
<output>9</output>
9 pages.
