Multiplying Fractions Using Cancellation

What is the first step in multiplying fractions using cancellation?

• Multiply the denominators

• Check for simplest form

• Cross-cancel if possible

• Multiply the numerators

When cross-cancelling, which numbers should you look at?

• Diagonal numerator and denominator

• Denominators only

• All numerators and denominators

• Numerators only

After cross-cancelling, what is the next step in multiplying fractions?

• Add the numerators

• Multiply the numerators

• Divide the fractions

• Subtract the denominators

Why is cross-cancellation useful when multiplying fractions?

• It simplifies the fractions before multiplying

• It eliminates the need to multiply

• It makes the numbers larger

• It changes the fractions to decimals

In the problem 2/5 x 5/7, which numbers can be cross-cancelled?

• 5 and 7

• 2 and 5

• 5 and 5

• 2 and 7

What should you do if no cross-cancellation is possible?

• Skip the problem

• Multiply the fractions as they are

• Convert to decimals

• Add the fractions

In the problem 2/9 x 3/4, which numbers can be cross-cancelled?

• 3 and 9

• None

• 2 and 4

• Both A and B

When multiplying three fractions, what is a key step to simplify the process?

• Convert to improper fractions

• Add all numerators first

• Multiply each fraction separately

• Cross-cancel across all fractions

In the bonus problem, which pairs of numbers were cross-cancelled?

• 3 and 9, 4 and 2

• 1 and 5, 2 and 3

• 3 and 5, 4 and 9

• 1 and 2, 5 and 9

What is the final step after multiplying the numerators and denominators?

• Add the results

• Check if the fraction is in simplest form

• Convert to a mixed number

• Divide the results
