Answer:
4 students
Step-by-step explanation:
what we know: 12 students, 2/3 are wearing blue, 1/6 are wearing red
first you have to make the fractions have the same denominator<em><u>(2/3=4/6)</u></em>
theres also 1/6 that are not wearing blue or red <u><em>(1/6+4/6=5/6, 6/6-5/6=1/6)</em></u>
so that makes it 2/6 of the students not wearing blue<em><u>(1/6+1/6=2/6)</u></em>
simplify<u><em>(2/6=1/3)</em></u>
1/3 of 12 is 4<u><em> (12÷3=4)</em></u>
the equations are in parentheses and bolded, italicized, underlined.
hope this helps :)
