We can multiply the two terms together and then reduce. We can also 'cross cancel" with common factors in the beginning and then multiply at the end. Most students prefer to multiply first and then simplify. I learned it through cross canceling. I'm going to sound like that OLD teacher right now... We cross cancelled back in my day because we didn't use the calculator so we wanted to keep the numbers as small as possible to make the computations easier. Remember, when doing division with fractions, you must change the division sign to multiplication and invert (use the reciprocal) of the 2nd fraction. Then you proceed using your multiplication rules. You might remember 3) 32f12 this as "keep, change, change" or "invert and multiply". 21Q15 27all 4) 16m 48m 10 12p10 In the video, we will do both practice problems BOTH WAYS. When you are doing the problems on your own, you choose whichever way you like best. Both ways are 100% acceptable, But remember, even though you can do the problem two different ways, there is only one correct answer to each problem.
