"Comparison of Fractions" PPT

Part One: Review

Review: Put ＞ or ＜ in the circle below.

2/3○1/3 3/7○1/7 5/9○4/9 2/5○4/5

Think about it: How do fractions with the same denominator compare? What if the denominators are different?

Example 1: Honghong and Liangliang read the book "The People's Good Police Officer - Ren Changxia".

The content was so touching that I read 1/2 of the book in one sitting.

I've read about 2/3 of this book.

Can be compared by converting them into fractions with the same denominator.

6 is a multiple of 2 and a multiple of 3, so it is called the common multiple of 2 and 3.

Converting a fraction with different denominators into a fraction with the same denominator that is equal to the original fraction is called a common fraction.
