Adding fractions - Math Tutoring Online - Math Skills

The video tutorial explains how to add fractions, starting with those that have common denominators and then moving to fractions with different denominators. It covers finding the lowest common denominator (LCD) and demonstrates the process of converting improper fractions to mixed numbers. The tutorial provides examples and step-by-step instructions to ensure understanding.

What is the first step when adding fractions with the same denominator?

• Add the numerators and keep the denominator the same

• Subtract the numerators

• Multiply the fractions

• Add the denominators together

Why is it important to have a common denominator when adding fractions?

• To make the fractions larger

• To simplify the fractions

• To ensure the fractions are equivalent

• To change the numerators

What is the Lowest Common Denominator (LCD) of 5 and 3?

• 15

• 30

• 5

• 10

When converting an improper fraction to a mixed number, what do you do with the remainder?

• Ignore it

• Place it over the original denominator

• Use it as the new denominator

• Add it to the numerator

How do you maintain the integrity of a fraction when changing its denominator?

• Only multiply the denominator

• Add the same number to both the numerator and denominator

• Only multiply the numerator

• Multiply both the numerator and denominator by the same number
