*Remember*
It is easy to compare fractions if they have the same denominator. All you have to do is to compare their numerators.
![Page 16: Topic 9 Review Test on Monday!!! FRACTIONS A fraction is one or more _______ of a whole that is divided into ________ parts. parts equal.](https://reader035.fdocuments.in/reader035/viewer/2022070404/56649f345503460f94c518d6/html5/thumbnails/16.jpg)
When the denominators are the same, simply compare the numerator.

![Page 17: Topic 9 Review Test on Monday!!! FRACTIONS A fraction is one or more _______ of a whole that is divided into ________ parts. parts equal.](https://reader035.fdocuments.in/reader035/viewer/2022070404/56649f345503460f94c518d6/html5/thumbnails/17.jpg)
What do you do when the denominators are not the same? You must find a common denominator. Least Common Multiple (LCM) For example 6/8 and 4/5
5: 5, 10, 15, 20, 25, 30, 35, 40, 45.....8: 8, 16, 24, 32, 40, 48, 56.....
![Page 18: Topic 9 Review Test on Monday!!! FRACTIONS A fraction is one or more _______ of a whole that is divided into ________ parts. parts equal.](https://reader035.fdocuments.in/reader035/viewer/2022070404/56649f345503460f94c518d6/html5/thumbnails/18.jpg)
For example 6/8 and 4/5
5: 5, 10,15, 20, 25, 30, 35, 40, 45.....8: 8, 16, 24, 32, 40, 48, 56.....
Do you see a common multiple???
40 Use 40 as the common denominator.
6/8 x = 30/40
4/5 x = 32/40 .
![Page 19: Topic 9 Review Test on Monday!!! FRACTIONS A fraction is one or more _______ of a whole that is divided into ________ parts. parts equal.](https://reader035.fdocuments.in/reader035/viewer/2022070404/56649f345503460f94c518d6/html5/thumbnails/19.jpg)
Another way is to multiply denominators
5
6
3
4
What are the two denominators?
4 x 6 = 24
4 and 6
The common denominator is 24.
