Question

Help with 21 and 24 those make no sense and I need those one for a test that I am studying for

Answer 1

Answer to 21 5 stands for left handers and 8 for right handers. Their are 45 left handers. 45/5 is 9. 9 times 8 is 72. for section b 5+8 is 13 so the answer is 5 over 13. Answer to 24 the table goes 1:5:7, 2:10:14,3:15:21, 4:20:28 on 7 graders the open spaces are 14 and 21 so their is 7 seventh graders for each moral. Their are 5 6th graders because on the first space their are 5 and it is one moral.
