While exercising ned walk 1/9 of a mile in 1/2 of an hour. at this rate, how far will ge travel after an hour?

1/9 :
1/2 : 1hour
Cross multiply-
1/9=1/2x
Solve the equation to find x, which is how far in one hour.
1/9 divided by 1/2 = 2/9
A simpler way to solve this SPECIFIC problem is that we know that two halves (1/2 1/2) is one. So, 1/2 x2 is 1. 1/9 x 2 is 2/9
2/9 mi in 1 hour

Using the rise/run rule. you would get 2/6.simp. 1/3
