Comparing and Converting Fractions

The video tutorial explains how to compare fractions with different denominators using greater than, less than, or equals symbols. It demonstrates that fractions can be compared by rewriting them with a common denominator, which doesn't necessarily have to be the least common denominator. The tutorial provides examples of comparing fractions such as 5/6 and 3/4, 3/4 and 7/9, and 5/6 and 7/9, using different common denominators to illustrate the process.

Why is it difficult to compare fractions with different denominators?

• Because they are improper fractions.

• Because they are mixed numbers.

• Because they have different denominators.

• Because they have different numerators.
