Question

Joe can eat 7 hot dogs in 20 minutes. SS BELOW

Answer 1

`(7)/(20)` =
`(14)/(40)`

Explanation:

We know

Joe can eat 7 hot dogs in 20 minutes.

How long would it take him to eat 14 hot dogs?

We see that the number of hot dogs is now doubled, so we double the 20 minutes too.

So, the answer is

`(7)/(20)` =
`(14)/(40)`
