Rob is setting up a model train track that is 3 and 3 over 8 feet long. No telephone pole is needed at the start of the track. However, along the track, he places a telephone pole every 3 over 8 foot apart. How many telephone poles does he need? (Input number values only) A N S W E R P L E A S E! limited time!

Wouldn't the answer be 1

First convert the mixed number 3 & 3/8 to an improper fraction

The whole part is w = 3

The numerator is n = 3

The denominator is d = 8

So we'll have the improper fraction (d*w+n) / d = (8*3+3) / 8 = (24+3) / 8 = 27/8

In other words, the mixed number 3 & 3/8 is equivalent to the improper fraction 27/8

The whole track is 27/8 feet long. Divide this entire length over the fraction 3/8 to figure out how many poles are needed

Number of poles needed = (length of entire track) / (distance between poles)

Number of poles needed = (27/8) divided by (3/8)

Number of poles needed = (27/8) times (8/3)

Number of poles needed = (27*8) / (8*3)

Number of poles needed = 27/3

Number of poles needed = 9

Therefore the final answer is 9
