Cross-multiply and then divide both sides by 68.

68(r)=12(4)
68r/68=48/68
r=12/17

68/12=4/r
68/12(r)=4 ; time r on both side
r=4(68/12) ; divide 68/12 to get r itself
r=48/68
or reduced r=12/17

r= 12/17

Cross multiply

68 * r = 12 * 4

68r = 48

r = 48/68

r = 12/17

a first step would be to simplify 68/12 which is "5 and 2/3" or "17/3"

Then, multiply both sides by r

17/3r = 4

Multiply both sides by 3/17

r=12/17

Hope i helped!
