How long would it take to lay 8 rows of 18 bricks each at a rate of 4 bricks per minute? Express your answer in hours.
:
Find total number of bricks: 8 * 18 = 144 bricks
Find number of minutes to do this: = 36 min
Change 36 min to hr: = .6 hrs

First figure out the total number of bricks you are going to lay. I hope "8 rows of 18 bricks" each suggests multiplication.

Next, figure out how many minutes it will take to lay that number of bricks. From "4 bricks per minute" I hope you understand that laying 4 bricks takes a minute, laying another 4 bricks will takes another minute, etc. So the number of minutes to do all the bricks will be how many sets of 4 bricks there are in the total you figured out in the first step. Taking a total and finding out how sets of 4 there are in it is a job for division (divide by 4).

Now you have the total number of minutes it will take. Each hour has 60 minutes in it. One set of 60 minutes is one hour, another 60 minutes is another hour, etc. So we again have a task of finding out how many sets of some number (60) there are in some total number. So again we will divide.

If you did the first two steps correctly, then you should have a total number of minutes that is less than 60. But this does not change that fact that we should divide! Just write a fraction. (Remember, fractions are a way of expressing a division.) Put the total number of minutes in the numerator and 60 in the denominator. This fraction is the number of hours it will take to do the job. (The fact that it is a fraction just means that it will take less than 1 whole hour to lay all the bricks.)

Last of all, reduce the fraction! (I've never met a teacher that did not want reduced fractions.)
