How to determine if ratios are equivalent or not

The video tutorial explains the concept of equivalent ratios, starting with an introduction and moving on to examples, such as comparing 1/2 to 2/4. It demonstrates how to prove ratios are equivalent by multiplying both the numerator and denominator by the same number. The tutorial also covers how to determine if given ratios are equivalent through calculation examples, emphasizing the importance of using a common multiplier.

What is an equivalent ratio to 1/2?

• 2/4

• 3/5

• 5/7

• 4/6

How can you determine if two ratios are equivalent?

• By multiplying both the numerator and denominator by the same number

• By dividing both the numerator and denominator by different numbers

• By subtracting the same number from both the numerator and denominator

• By adding the same number to both the numerator and denominator

What is the first step in checking if 21/98 is equivalent to another ratio?

• Multiply both the numerator and denominator by the same number

• Multiply the numerator by 3

• Divide the numerator by 7

• Add 7 to both the numerator and denominator

If 7 * 14 equals 98, what does it imply about the ratios 21/98 and 7/14?

• They are not equivalent

• They are equivalent

• They are both less than 1

• They are both greater than 1

What should you do if you cannot calculate the equivalence of ratios in your head?

• Add the numbers together

• Use the old method of multiplication

• Guess the answer

• Use a calculator
