Subtracting Fractions with Unlike Denominators

The video tutorial explains how to subtract fractions, focusing on the importance of like denominators. It begins with an introduction to fractions and the concept of like denominators. The tutorial then covers the process of subtracting fractions with like denominators, including simplification. For fractions with unlike denominators, it explains how to find the least common multiple and create equivalent fractions. The video provides examples to illustrate these concepts and concludes with a summary and tips for successful subtraction of fractions.

What is the first step in subtracting fractions with like denominators?

• Add the numerators

• Subtract the numerators

• Multiply the denominators

• Divide the numerators

When fractions have unlike denominators, what must you find first?

• Greatest common factor

• Least common multiple

• Sum of the numerators

• Difference of the denominators

How do you create equivalent fractions with a new denominator?

• Divide both numerator and denominator by the same number

• Subtract the same number from both numerator and denominator

• Multiply both numerator and denominator by the same number

• Add the same number to both numerator and denominator

In the example of subtracting 2/3 and 1/2, what is the least common multiple of the denominators?

• 5

• 6

• 3

• 2

What is the result of subtracting 5/6 and 1/4 after finding a common denominator?

• 7/12

• 1/12

• 5/12

• 3/12

Why is it important to simplify the result after subtracting fractions?

• To make the fraction easier to understand

• To change the value of the fraction

• To increase the numerator

• To decrease the denominator

What should you do if the fractions do not have like denominators?

• Ignore the denominators

• Multiply the fractions

• Find the least common multiple and create equivalent fractions

• Add the fractions directly
