At a pet store, davina counted 12 parrots out of 20 birds. which is an equivalent ratio of parrots to birds at the pet store? 2: 3 3 to 2 mc004-1.jpg 3 to 5

3 to 5

Explanation:

As you can see the ratio of parrots to birds is actually first 12:20, we can reduce that number to the smallest possible by dividin it, the ideal would be to leave the ratio on a 1 to something, but if we can´t do it on whole numbers we have to leave the smallest whole number possible.

So 12 and 20 are both divisible by two, we can do that, and then be left with:

6:10, we can divide it again by 2:

3:5, so as we can´t actually divide it any further, that would be the ratio.
