Equivalent Ratios and Simplification

Mr. Buffington from Simplify Academy explains how to determine equivalent ratios using two methods: simplifying and cross multiplying. He demonstrates each method with examples, encouraging students to practice and choose their preferred method. Simplifying involves reducing fractions to their simplest form, while cross multiplying checks equivalence by comparing products. Both methods are essential skills for understanding ratios and fractions.

What are the two methods discussed in the lesson for checking equivalent ratios?

• Simplifying and cross-multiplying

• Adding and subtracting

• Multiplying and dividing

• Squaring and cubing

What does an equivalent ratio look like?

• 5/10 equals 4/5

• 5/10 equals 1/2

• 5/10 equals 2/3

• 5/10 equals 3/4

What is the first step in simplifying a fraction?

• Subtract the numerator from the denominator

• Multiply the numerator and denominator

• List the factors of the numerator and denominator

• Add the numerator and denominator
