How to determine if two ratios are equivalent

The video tutorial explains how to determine if two ratios are equivalent by using a multiplier. It demonstrates the process of multiplying both terms of a ratio to see if they match another ratio, confirming their equivalence. The example used involves multiplying the terms of the ratio 8:72 by 9 to match the ratio 72:81, showing they are equivalent. The tutorial concludes with a reference to a textbook problem.

What is the primary goal when working with equivalent ratios?

• To convert the ratios into percentages

• To divide the ratios by a common factor

• To determine if the ratios are equal

• To find the sum of the ratios

What is the first step in determining if two ratios are equivalent?

• Subtract the denominators

• Find a common multiplier

• Convert them to decimals

• Add the numerators

If you multiply the numerator of a ratio by 9, what must you do to the denominator?

• Multiply it by 9

• Divide it by 9

• Subtract 9 from it

• Add 9 to it
