Question

$1 A class consists of 1 3 freshmen, a sophomores, and 3 juniors, the rest are seniors. What fraction of the class is seniors?$

Answer 1

Answer #1

A class consists of

$freshmen=\frac{1}{3}\:;sophomores=\frac{1}{6}\:;juniors=\frac{1}{3}$

Rest all are seniors then the seniors in the class is :-

$seniors \:fraction=1-\frac{1}{3}-\frac{1}{6}-\frac{1}{3}\Rightarrow 1-\frac{5}{6}$

Hence the senior fraction in the class is=1/6
