Given Two-thirds of the students in a class are wearing blue jeans
.Or
Of students wear blue Jeans.
Number of students wearing red shirts is Two-sixths of the students who are wearing blue jeans .
Number of students wearing red shirts = ![\frac{2}{6} of\frac{2}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B6%7D%20of%5Cfrac%7B2%7D%7B3%7D%20%20%20)
Simplifying we have:
Fraction of the students in the class are wearing blue jeans red shirts =![\frac{2}{9}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B9%7D%20%20)
