Shirts

In a classroom, 1/6 of the students are wearing blue shirts and 2/3 are wearing white shirts. There are 36 students in the class. How many students are wearing a shirt other than blue or white?

Correct answer:

x =  6

Step-by-step explanation:

$$\begin{gathered} n=36 \\ b=n\cdot {\displaystyle \frac{1}{6}}=36\cdot {\displaystyle \frac{1}{6}}=6 \\ w=n\cdot {\displaystyle \frac{2}{3}}=36\cdot {\displaystyle \frac{2}{3}}=24 \\ x=n-b-w=36-6-24=6 \end{gathered}$$
