Math tutorial video for adding two fractions with unlike denominators

The video tutorial explains how to add and subtract fractions with unlike denominators by finding the least common denominator (LCD). It covers the process of determining the LCD, multiplying both the numerator and denominator to create equivalent fractions, and finally adding the fractions once they have a common denominator.

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

• Add the numerators directly

• Find the least common denominator

• Multiply the numerators

• Subtract the smaller denominator from the larger one

What is the least common denominator of 5 and 6?

• 15

• 30

• 60

• 10

Why do we multiply both the numerator and the denominator by the same number?

• To simplify the fraction

• To change the value of the fraction

• To make the fraction larger

• To keep the fraction equivalent

If a fraction has a denominator of 5, what should you multiply it by to get a denominator of 30?

• 2

• 6

• 5

• 3

What is the result of adding 18/30 and 10/30?

• 28/30

• 18/40

• 10/30

• 28/60
