For every 4 miles vanessa jogged, cody jogged 3 miles. if vanessa jogged 1 miles, how far would cody have jogged?

What we know:
For every 4 miles Vanessa jogs, Cody jogs 3 miles   = 4/3

What we need to find: if Vanessa jogs 1 mile how far does Cody jog = 1/x where x represents Cody's miles.

Set up a proportion:
4/3 = 1/x
(4)(x)=(3)(1)              cross multiply
4x=3
4/4x=3/4                    multiplicative inverse
x=3/4 mile

If Vanessa jogged 1 mile, then Cody jogged 3/4 of a mile.
