Understanding Equivalent Fractions

The video tutorial reviews the concept of equivalent fractions, explaining that they represent the same part of a whole. It demonstrates this with a visual example using rectangles and explains how to verify equivalence through cross multiplication. The tutorial also covers how to generate a series of equivalent fractions by multiplying both the numerator and denominator by the same number. The video concludes with a recap of the key points discussed.

What do equivalent fractions represent?

• Different parts of the same whole

• The same part of the same whole

• The same part of different wholes

• Different parts of different wholes

In the rectangle example, what fraction of the rectangle is blue in the first case?

• 1/3

• 1/2

• 1/4

How do you determine if two fractions are equivalent using cross-multiplication?

• By subtracting the denominators

• By dividing the fractions

• By adding the numerators

• By checking if the cross-products are equal

What is the first step in finding equivalent fractions?

• Add the numerator and denominator

• Subtract the numerator from the denominator

• Divide the numerator by the denominator
