Cross Cancellation Techniques in Fraction Multiplication

What is the primary benefit of using cross-cancellation when multiplying fractions?

• It reduces the size of numbers we work with before multiplication.

• It eliminates the need for multiplication.

• It simplifies the fractions after multiplication.

• It changes the fractions into whole numbers.
