Operations with Fractions

The video tutorial covers operations with fractions, including addition, subtraction, multiplication, and division. It starts with operations involving equal denominators and progresses to those with different denominators. The tutorial explains the concept of the least common multiple (LCM) for addition and subtraction with different denominators and demonstrates the reciprocal method for division. The video concludes with solving complex expressions involving multiple fraction operations.

If you have two fractions with the same denominator, how do you add them?

• Add both the numerators and denominators

• Subtract the numerators and keep the same denominator

• Add the numerators and keep the same denominator

• Multiply the numerators and add the denominators
