Camille spent 22 minutes and 30 seconds opening presents.
Since Camille had a very fun birthday party with lots of friends and family attending, and the party lasted for 3 hours, and she and her friends played games for 3/8 of the time, ate pizza and cake for 50% of the time , and spent the remainder of the time opening presents, to determine the amount of time spent opening presents the following calculation must be performed, posing the following linear equation:
Total time - time spent on other activities = time spent opening presents
3 - (3 x 3/8) - (3 x 0.5) = X
3 - 1.125 - 1.5 = X
3 - 2.625 = X
0.375 = X
1 = 60
0.375 = X
0.375 x 60 = X
22.5 = X
Therefore, Camille spent 22 minutes and 30 seconds opening presents.
In order to compare you must multiply the the bottom two by each other and then multiply the top one by the same number you multiplied the bottom one by. The answer is not equal because the first fraction is 6/15 and the second is 5/12.
