Anna is making a fertilizer mix for her flower garden. she uses 2 cups of fertilizer to 12
quarts of water. how much fertilizer does anna need to make 15 gallons of the mixture?

10 cups of fertilizer

Step-by-step explanation:

2 cups fertilizer = 12 quarts water

so, 1 cups fertilizer means = 12/2 = 6 quarts of water

Now, 15 gallons to quarts would be:

4 quart = 1 gallons

So,

15 gallon = 4 * 15 = 60 quarts

So, we are essentially asking:

How many cups of fertilizer we need for 60 quarts

The ratio is 1 cup = 6 quarts

So, 60/6 = 10 cups is 60 quarts

We would need 10 cups of fertilizer to make 15 gallons of mixture
