To maintain a ratio of 2 teaspoons of liquid soap to 3 gallons of water, AJ, with 3 tablespoons of liquid soap, needs 13.5 gallons of water. This is calculated by converting tablespoons to teaspoons and applying the given ratio.
If AJ uses a ratio of 2 teaspoons of liquid soap for every 3 gallons of water, and he has 3 tablespoons of liquid soap, we need to convert tablespoons to teaspoons since 1 tablespoon is equivalent to 3 teaspoons.
![\[ 3 \, \text{tablespoons} * 3 \, \text{teaspoons/tablespoon} = 9 \, \text{teaspoons} \]](https://img.qammunity.org/2022/formulas/mathematics/college/tb192i1gvkby4bp3c80b9qnx6g74um3sey.png)
Now, using the given ratio, for every 2 teaspoons of liquid soap, AJ needs 3 gallons of water. Therefore, for 9 teaspoons of liquid soap:
![\[ \text{Gallons of water} = \frac{9 \, \text{teaspoons} * 3 \, \text{gallons/teaspoon}}{2} = 13.5 \, \text{gallons} \]](https://img.qammunity.org/2022/formulas/mathematics/college/gr0q1tz7y78a6b32iquqq2ie39vu1yxtr9.png)
AJ should use 13.5 gallons of water to mix with 3 tablespoons of liquid soap.
