Question

Your high school freshman class consists of 760 students. In recent years only 4 out 7 students actually graduated in four years. Approximately how many of your classmates are expected to graduate in four years

Answer 1

760 total students....4 out of 7 graduated...3 out of 7 didn't

so 4/7(760) = 3040/7 = 434.28 <== so approx. 434 will graduate
and 3/7(760) = 2280/7 = 325.7...and approx. 326 won't graduate
