Question

Rob is setting up a model train track that is 3 3/8 feet long no telephone pole is needed at the start of the track. However along the track he places a telephone pole every 3/8. Foot a part. How many telephone poles dose he need

Answer 1

First we need to convert 3 3/8 into 1/8ths:


`3 (3)/(8) = (27)/(8)`

Now, we need to see how many times 3/8 goes into 27/8:


`(27)/(8) / (3)/(8) = 27 / 3 = 9`

So we know he needs 9 telephone poles
