**Given :**

Teresa is going to make 3 batches of cookies.

She needs 3/4 milk for each. Her measuring cup only holds 1/4 gallon.

**To Find :**

How many times will she need to fill up.

**Solution :**

Amount of milk need per batch, A = 3/4 gallon.

Measuring cup only holds, m = 1/4 gallon.

Number of times she need to fill up,

n = A/m = (3/4)/(1/4) = 3

Now, number of batches are three.

So, number of time she need to fill up in three batch.

**Therefore, this is the required solution.**
