Ann's and Deb's astronomy classes are going on a field trip to see the night sky. Ann's class has 9 telescopes for 21 students. Deb's class has 12 telescopes for 28 students. Which class has the greater ratio of telescopes to students?

Respuesta :

Answer: Neither, the two classes have the same amount of telescopes.

Step-by-step explanation:

ANN = 9 telescopes / 21 students

DEB = 12 telescopes / 28 students

Times Ann's ratio by 1/3 (basically dividing by 3)

9(1/3) / 21(1/3 = 3/7

Times Deb's ratio by 1/4 (diving by 4)

12(1/4) / 28(1/4) = 3/7

Since they are the same, neither class has more telescopes. Again, hope this is right and if not sorry.
