Jade ran six times around her neighborhood to complete a total of one mile. How many times will she need to run to complete 5/6 of a mile

-- 6 laps around the neighborhood  =  1 mile

-- Each lap  =  1/6 of a mile.

-- 5/6 of a mile requires 5 laps.

==========================================

Using a proportion:

                       ('L' laps) / (5/6 mile)  =  (6 laps) / (1 mile)

Cross-multiply the proportion:

                       L lap-mile  =  (6) x (5/6) lap-mile

Divide each side by  mile :

                         L lap  =  (6) x (5/6) lap  =  5 lap

 
the answer would be 5 laps because 1 miles= 6 laps and she needs to run 1 less then that.
