Painting 9

Maria and Emme each had 4 pints of paint. On the first day of painting, Maria used 3/5 of her 4 pints of paint, and Emme used 3/4 of her 4 pints of paint. How much of Maria and Emme's paint remained after the first day of painting? Enter your answer as a mixed number.

Correct answer:

x =  2 ³⁄₅ = 13/5

Step-by-step explanation:

$$\begin{gathered} m=4-4\cdot \frac{3}{5}=\frac{8}{5}=1\frac{3}{5}=1.6 \\ e=4-4\cdot \frac{3}{4}=1 \\ x=m+e=\frac{8}{5}+1=\frac{8}{5}+\frac{1\cdot 5}{5}=\frac{8}{5}+\frac{5}{5}=\frac{8+5}{5}=\frac{13}{5}=2\frac{3}{5}=2.6 \end{gathered}$$
