Shirts

In a classroom, 1/6 of the students wear blue shirts, and 2/3 wear 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:

$$\begin{gathered} n=36 \\ b=n\cdot \frac{1}{6}=36\cdot \frac{1}{6}=\frac{36\cdot 1}{6}=\frac{36}{6}=6 \\ w=n\cdot \frac{2}{3}=36\cdot \frac{2}{3}=\frac{36\cdot 2}{3}=\frac{72}{3}=24 \\ x=n-b-w=36-6-24=6 \end{gathered}$$
