Juanita is mixing orange and blue paint to make yellow paint. She has 5/8

Question

of a gallon of blue paint, but she needs 7/8
of a gallon. How much more blue paint does she need? Simplify the answer.

Answer 1

To find out how much more blue paint Juanita needs, we can subtract the amount of blue paint she currently has from the amount she needs.

She needs \( \frac{7}{8} \) of a gallon of blue paint and currently has \( \frac{5}{8} \) of a gallon.

We can set up the subtraction:

\[ \frac{7}{8} - \frac{5}{8} \]

Since the denominators are the same, we subtract the numerators:

\[ \frac{7 - 5}{8} = \frac{2}{8} \]

Now we simplify \( \frac{2}{8} \):

\[ \frac{2}{8} = \frac{1}{4} \]

Therefore, Juanita needs \( \frac{1}{4} \) of a gallon more blue paint.
