Adding Tenths and Hundredths by Creating Equivalent Fractions

The video tutorial explains how to correctly add fractions with different denominators by creating equivalent fractions. It begins by illustrating the incorrect method of adding numerators and denominators directly. The tutorial then demonstrates how to create common denominators using visual models and numerical methods. It provides example problems to reinforce the concept of finding equivalent fractions and adding them correctly.

Why can't you simply add the numerators and denominators of fractions with different denominators?

• Because the denominators must be multiplied

• Because the numerators must be subtracted

• Because fractions cannot be added

• Because it would result in an incorrect fraction

What is the first step in adding fractions with different denominators using a visual model?

• Convert fractions to have a common denominator

• Add the numerators directly

• Multiply the fractions

• Subtract the smaller fraction from the larger one

How do you convert 3/10 to an equivalent fraction with a denominator of 100?

• Divide both numerator and denominator by 10

• Subtract 10 from both numerator and denominator

• Add 10 to both numerator and denominator

• Multiply both numerator and denominator by 10
