Question

Charlie Brown walks his dog Snoopy every day. He walks 1/2 of a mile every 1/8 of an hour. How many miles per hour does he walk with Snoopy?

Answer 1

4 miles per hour

Explanation:

`\frac{(1)/(2) }{\frac{}{8} }` Which can be written

`(1)/(2)` ÷
`(1)/(8)` There are a couple of ways to do this. I think that the most intuitive way is to get a common denominator and then divide.

`(1)/(2)` x
`(4)/(4)` =
`(4)/(8)` Anther name for
`(4)/(4)` is one. I used that to make an equivalent fraction

`(4)/(8)` ÷
`(1)/(8)` =
`((4)/(1) )/((8)/(8) )` =
`(4)/(1)` = 4
