Question

in a classroom, \\(\frac{3}{10}\\) of the students are wearing blue shirts, and \\(\frac{3}{5}\\) are wearing white shirts. there are 20 students in the classroom. how many students are wearing shirts other than blue shirts or white shirts? solve on paper. then check your work on zearn. \\(\square\\) students are wearing shirts other than blue shirts or white shirts.

Explanation:

Step1: Find blue-shirt students

Calculate number of students in blue shirts:
$\frac{3}{10} \times 20 = 6$

Step2: Find white-shirt students

Convert $\frac{3}{5}$ to tenths, then calculate:
$\frac{3}{5} = \frac{6}{10}$, so $\frac{6}{10} \times 20 = 12$

Step3: Sum blue+white students

Add the two groups together:
$6 + 12 = 18$

Step4: Calculate other-shirt students

Subtract total from class size:
$20 - 18 = 2$
