In order to find a equivalent ratio, first lets figure out the ration.
12:3 =
.
12/3 =
4.
Since 12/3 = 4 ( same as well with the ratio ).
Since, we also want to find equaivalent we would put it in to this equation…
84/4 =
21.
( To make sure our answer it right: )
21x4 =
84.
The equivalent ratio to this problem would equal:
12:3 = 84:21
