Comparing and Converting Fractions

This video tutorial teaches how to compare fractions by creating common denominators. It explains the components of fractions, common mistakes in comparing them, and the process of finding common denominators using the least common multiple. The tutorial also covers converting fractions to have common denominators and ordering them from least to greatest.

Why is it important to have common denominators when comparing fractions?

• To make fractions look similar

• To change the numerators

• To ensure fractions are from the same whole

• To simplify fractions

What does the numerator in a fraction represent?

• The number of parts you have

• The total number of parts

• The number of equal parts in a whole

• The size of each part

What is a common mistake when comparing fractions with different denominators?

• Comparing only the denominators

• Ignoring the numerators

• Assuming fractions are equal if numerators are the same

• Using the least common multiple

What is the least common multiple (LCM) used for in fraction comparison?

• To simplify fractions

• To find a common denominator

• To find a common numerator

• To convert fractions to decimals

How do you find the least common multiple of denominators?

• By skip counting and finding a common number

• By adding the denominators

• By subtracting the denominators

• By multiplying the denominators

What must you do to both the numerator and denominator when converting fractions to have a common denominator?

• Subtract the same number

• Divide by the same number

• Multiply by the same number

• Add the same number

If you multiply the denominator by 10, what should you do to the numerator?

• Add 10 to it

• Divide it by 10

• Multiply it by 10

• Multiply it by 5

What is the new fraction for two-thirds when converted to have a denominator of 30?

• 10/30

• 20/30

• 15/30

• 25/30

Which fraction is the smallest when converted to have a common denominator of 30?

• 18/30

• 20/30

• 15/30

• 24/30

What is the correct order of the fractions one-half, two-thirds, and four-fifths from least to greatest?

• Four-fifths, two-thirds, one-half

• One-half, two-thirds, four-fifths

• One-half, four-fifths, two-thirds

• Two-thirds, one-half, four-fifths
