At Washington Elementary School, the sixth grade teachers are giving a prize to each student who does all their homework for a week. Mr. Price is trying to figure out how many students are in sixth grade so that he knows how many : prizes to buy. There are 26 kids in Ms. Wright's class, 28 kids in Mrs. Lynn's class, 25 kids in Ms. Render's class, and 27 kids in Mr. Price's class. Mr. Price goes to the store and buys 13 bags. In each bag there are 11 prizes. In Ms. Wright's class, 1/2 of the students did all of their homework. In Mrs. Lynn's class, 3/4 of the students did all of their homework. In Ms. Render's class, 4/5 of the students did all of their homework. In Mr. Price's class, 7/9 of the students did all of their homework. Mr. Price takes the remaining prizes and gives half of them to the fifth grade teachers. How many prizes did Mr. Price give to fifth grade?
