Answer:

12 red jelly beans

Step-by-step explanation:

Given :


(Red)/(Yellow) =
(4)/(5)


(Yellow)/(Blue) =
(3)/(7)

Notice :


(Red)/(Yellow) x
(Yellow)/(Blue) =
(Red)/(Blue)

Hence


(Red)/(Blue) =
(4)/(5) x
(3)/(7)


(Red)/(Blue) =
(12)/(35)

or re-written in another way:

Red : Blue --> 12:35

If there were 35 blue jelly beans, then by observation of the ratio of Red:Blue, there will be 12 red jellybeans
