Question

Please help and show all the work. I need all the work to be explained as the teacher asked. Thank you so much for the help.

Answer 1

17. Because there need to be 4 equal rows, we can divide 24 by 4. This gives us 6 chairs per row.

18. We can do this one by checking each fraction. Let's start from the bottom. 1/4th is equal to .25. 2/2 is equal to 1. 4/4 is equal to 1. 4/1 is equal to 4, so A has to be the answer.

19. 8 students liked pizza, 6 students chose hamburger, 3 students chose spaghetti, and 5 students chose tacos. We add up the students who chose pizza and hamburgers to get 14, and we add together the students who chose spaghetti and tacos to get 8. Now, we subtract the amount of students who chose spaghetti and tacos from the amount of students who chose pizza or hamburgers. This is 14-8, or 6. Answer D.

Answer 2

17. You need to know the number of chairs in a row, so 24/4 = 6. So B.
18. Anything over 1 is itself, so 4/1 = 4. A.
19. 6+8 = 14 people like pizza/hamburgers. 3+5 =8 people like spaghetti/tacos. 14-8 = 6. D.
