Step-by-step explanation:

If 3 x 4 = 12 then you need to do the same to the number 4 so 4 x 4 =16

3 : 4 :: 12 : x proportion 3x = 48 product means/extremes Can you solve for x and answer?

(If not look below.)

Step-by-step explanation:

ratio: 3:4

so divide 12 by 3=4

and multiply 4 by 4=16

your friend sells 16 tickets

ratio is now 12:16

4 : 3 = 12 : x

x = 12 * 4  / 3  = 16
