Answer:

  • 3 : 1
  • 9 : 3

Step-by-step explanation:

Find the unit rate:

Remember, the unit rate is when one of the numbers in a ratio is 1.

27 : 9

(divide by the 9 on both sides)

3 : 1

Great, we have one equivalent ratio! Let's find another.

Now, multiply both sides by any number. For example, let's use 3.

3 : 1

(multiply by 3 on both sides)

9 : 3

We found a second equivalent ratio! Hope this helps :)
