if 80ml of pesticide of needed in 1 gallon of water, how many ml of pesticide is needed in 3 oz of water?

To determine how many milliliters of pesticide are needed in 3 ounces of water, we first need to establish the concentration of pesticide per unit of water and then apply it to the 3 ounces.

### Step 1: Find the concentration
You know that 80 milliliters (ml) of pesticide is needed for 1 gallon of water. Since there are 128 ounces in 1 gallon, the concentration of pesticide per ounce of water is:

\[
\text{Concentration per ounce} = \frac{80 \text{ ml}}{128 \text{ oz}} = 0.625 \text{ ml/oz}
\]

### Step 2: Calculate the amount of pesticide for 3 ounces
Now, multiply the concentration by the number of ounces:

\[
\text{Pesticide needed for 3 oz} = 0.625 \text{ ml/oz} \times 3 \text{ oz} = 1.875 \text{ ml}
\]

So, **1.875 ml of pesticide** is needed for 3 ounces of water.
