When I told Roscoe you guys were working on fractions, he gave me the stink eye:
:) Anyway. Onto more fraction stuff.
Fortunately, it's quite easy to multiply fractions. All you need to do is multiply the tops, multiply the bottoms, and then simplify.
The example @ the bottom of pg. 252 sums it up quite well:
3/7 x 4/5 --- First, multiply the tops. 3 x 4 = 12, so our new numerator is 12.
---- Next, multiply the bottoms. 7 x 5 = 35, so our new denominator is 35.
---- If we put our new numbers together, our fraction is 12/35.
Since 12/35 is already in simplest form, 12/35 is our answer. You just have to remember to simplify after you've multiplied if the fraction is not already in simplest form.
Sometimes, to make life a little easier, you can simplify fractions BEFORE you multiply. Read through example 2 on pg. 253 as a class to see how it works.
If you encounter a mixed number, simply transform it into an improper fraction and then multiply. This can be seen in example 3 on pg. 253. Please read through this example as a class as well - you won't be solving too many word problems for fractions in the near future, but this is actually one of those times when, if you said, "Are we EVER going to use this outside of school?!?!" I can say, "Most likely." :) Fractions are everywhere.
I have a feeling some of you might be totally fine with this concept but will get stuck when you see negative numbers. REMEMBER your negative rules! :) Work on pg. 255, 1 - 13 today. If you finish early you can try the quick checks.
Tomorrow I will post the rest of 5-4 (Dividing Fractions). It's actually pretty easy!
tell roscoe i do that to
ReplyDeleteRosco Is so cute! And nice name!
