Problem number 5. How many sets of 12 minutes are there in 12 hours?  So to solve this problem, let's count the number of minutes in 12 hours and divide it by 12, since that's the number of sets of 12 minutes there will be.  There are 60 minutes in 1 hour, so the number of minutes in 12 hours is 12 times 60.  We don't actually have to multiply this out, because we will need to do 12 times 60 and then divide it by 12.  However, you can notice that since there is a 12 in the numerator and a 12 in the denominator, they actually cancel out and the number we're left with is 60.  So that means that the answer is A, 60.

Video Summary

The video explains how to determine the number of 12-minute sets in 12 hours. By calculating the total minutes in 12 hours (12 x 60), and dividing by 12, you find the sets. The multiplication and division involving 12 cancel each other, leaving 60 sets of 12 minutes in 12 hours. Thus, the answer is 60.
