Multiplying and Simplifying Fractions

The video tutorial explains how to multiply fractions by multiplying the numerators and denominators straight across. It then demonstrates how to simplify the resulting fraction by dividing both the numerator and denominator by their greatest common divisor. The final simplified answer is presented as 5/9.

What is the first step in multiplying two fractions?

• Divide the numerators and denominators

• Add the numerators and denominators

• Multiply the numerators and denominators

• Subtract the numerators and denominators

If you multiply the numerators 2 and 5, what is the result?
