Comparing Mixed Numbers and Fractions

The video tutorial explains how to compare mixed numbers by first reviewing what a mixed number is, which consists of a whole number and a proper fraction. It then demonstrates how to compare mixed numbers with different whole numbers and introduces the cross multiplication method for comparing fractions when the whole numbers are the same. The tutorial also covers converting fractions to equivalent fractions to verify comparisons. Finally, it provides examples and concludes with a summary of the methods discussed.

What is a mixed number?

• A number that is only a whole number

• A number that is only a fraction

• A number that combines a whole number and a fraction

• A number with a decimal point

When comparing mixed numbers, what should you look at first?

• The numerator of the fraction

• The decimal equivalent

• The whole number

• The proper fraction

What is the first step in comparing mixed numbers?

• Compare the whole numbers

• Convert them to improper fractions

• Compare the denominators

• Compare the numerators

If two mixed numbers have the same whole number, what should you compare next?

• The numerators of the fractions

• The denominators of the fractions

• The proper fractions

• The decimal equivalents

What should you do if the whole numbers in mixed numbers are equal?

• Convert to improper fractions

• Compare the numerators

• Compare the denominators

• Compare the proper fractions

What is cross multiplication used for?

• To compare fractions

• To divide fractions

• To subtract fractions

• To add fractions

How do you perform cross multiplication?

• Multiply the numerator of one fraction by the denominator of the other

• Multiply the numerators together

• Multiply the denominators together

• Add the numerators and denominators

In the example of 4 and 3/8 compared to 4 and 5/16, which is greater?

• 4 and 3/8

• 4 and 5/16

• They are equal

• Cannot be determined

Why is cross multiplication a faster method?

• It avoids subtracting fractions

• It avoids adding fractions

• It avoids converting to decimals

• It avoids finding common denominators

What is the result of multiplying 3 by 16 in the cross multiplication example?

• 56

• 32

• 48

• 40
