Cross Simplifying Fractions

The video tutorial explains the concept of cross simplifying fractions before multiplying them. It provides three examples: two ninths and three fourths, three tenths and two thirds, and five twenty-fourths and eight fifteenths. The tutorial demonstrates how cross simplifying can make calculations easier and result in already simplified fractions. The video concludes by highlighting the benefits of using this method.

What is the first step in cross simplifying fractions?

• Multiply the fractions directly.

• Subtract the fractions.

• Simplify each fraction separately.

• Add the fractions together.

When multiplying fractions, what is the traditional method?

• Subtract the numerators and denominators.

• Cross multiply and then simplify.

• Multiply straight across and then simplify.

• Add the numerators and denominators.

In the example of two-ninths and three-fourths, what is the simplified form of two-fourths?

• One-half

• Three-fourths

• One-third

• Two-thirds

What is the simplified form of three-ninths?
