Serena is mixing paint if she adds 1/4 gallon blue 1/4 gallon red and 1/4 gallon white how much total paint does she have

To find the total amount of paint that Serena has mixed, you can simply add the amounts of each color together:

\[
\frac{1}{4} \text{ gallon (blue)} + \frac{1}{4} \text{ gallon (red)} + \frac{1}{4} \text{ gallon (white)} = \frac{1}{4} + \frac{1}{4} + \frac{1}{4}
\]

This is the same as:

\[
\frac{3}{4} \text{ gallon}
\]

Therefore, Serena has a total of \( \frac{3}{4} \) gallon of paint.
