Comparing Fractions with Different Denominators

The video tutorial provides practice in comparing fractions with different denominators. It demonstrates how to compare fractions by finding a common denominator, using examples such as 2/4 vs. 5/12 and 3/5 vs. 2/3. The tutorial explains the process of rewriting fractions to have the same denominator and then comparing the numerators to determine which fraction is larger.

What is the first step in comparing fractions with different denominators?

• Add the fractions

• Find a common denominator

• Multiply the numerators

• Find a common numerator

How do you rewrite 2/4 so it has the same denominator as 5/12?

• Multiply the numerator by 3 and the denominator by 4

• Multiply both numerator and denominator by 2

• Divide both numerator and denominator by 2

• Multiply both numerator and denominator by 3

What operation do you perform on both the numerator and denominator to find an equivalent fraction?

• Division

• Addition

• Subtraction

• Multiplication
