Mỹ Le answered 4/3/2012 24 Fifth Grade Students Came To School. That Was Only 2/3 Of The Total Class. The Rest Were Home Sick. How Many Were Sick? EXPLAIN YOUR ANSWER. 12 were home sick. It said that 2/3 of 24 fifth graders were present, if you divide 24 by 2 then it's 12. Add the other 1/3 to the 2/3 it will be 36, so the answer is 12.
