Question

I NEED HELP PLSSSS!
.

Answer 1

so i’m not sure if there is a different way to do this but here’s how i did it:

start with 2:5

then just keep going up till you can add both numbers and get 28

so next i multiplied both sides by 2 to keep the ratio and got 4:10

then i went back and tried again and tried multiplying 3

which is 6:15.

that only is 21 students so it’s not right

next i tried 4

2 x 4 = 8

and

5 x 4 = 20

8:20 is still a 2:5 ratio and

8 + 20 = 28

so 8 students were in the teachers play

let me know if i can clarify anything

Answer 2

yes!! u r correct an no need for anything else i’m sure ur right and no need to clarify
