Addition and Subtraction of Fractions

The video tutorial covers the basics of working with fractions, focusing on addition and subtraction. It begins with adding fractions with the same denominator, emphasizing that only numerators are added. The tutorial then explains how to handle fractions with different denominators by finding the least common multiple (LCM). Subtraction follows a similar process. The video also includes examples of more complex fraction operations and concludes with a call for further practice.

When adding fractions with the same denominator, what should you do with the numerators?

• Subtract them

• Add them together

• Divide them

• Multiply them

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

• Add the numerators directly

• Find the least common multiple of the denominators

• Multiply the fractions

• Subtract the smaller denominator from the larger one

If you have fractions 1/3 and 1/4, what is their least common multiple?

• 9

• 6

• 12

• 15

How do you handle subtraction of fractions with different denominators?

• Add the fractions first

• Multiply the fractions first

• Find the least common multiple and adjust the fractions

• Subtract the numerators directly

What is the result of subtracting 3/5 from 7 using the least common multiple method?

• 11/35

• 21/35

• Negative 21/35

• Negative 11/35
