Rick is setting up a model train track that is 5 and 3 over 5feet long. No telephone pole is needed at the start of the track. However, along the track, he places a telephone pole every 4 over 5foot apart. How many telephone poles does he need? (Input number values only)

(5 3/5) / (4/5) =

28/5 / 4/5 =

28/5 x 5/4 =

140 / 20 =7

7 - 1 =6 poles Rick needs to erect.
