Mac painter

Mac is mixing red and white paint to make pink for his candy painting. He uses 1/4 ounces of red paint and 2/3 ounces of white paint. How many ounces of paint did he use?

Correct answer:

x =  0.9167 oz

Step-by-step explanation:

$$\begin{gathered} a=\frac{1}{4}=0.25\text{oz} \\ b=\frac{2}{3}\doteq 0.6667\text{oz} \\ x=a+b=\frac{1}{4}+\frac{2}{3}=\frac{3}{12}+\frac{8}{12}=\frac{3+8}{12}=\frac{11}{12}=\frac{11}{12}\text{oz}=0.9167\text{oz} \end{gathered}$$
