Three ladders measure 5 3/4 meters, 4 1/2 meters, 7 2/3 meters in length. What is the difference between the longest and shortest lengths?
The question we were asked was what is the difference between the longest and the shortest length ( 7 2/3 41/4). First we had to find the information we needed, witch was the longest and shortest length. next we had to get our denominators the same. Once you get there you have to subtract to get the difference between the two.
We new we did not have to regroup because,we found (LCM) Lest common denominator. We found that the denominator could be subtracted because, the larger number is on top.
That is how we solved our problem!
