Given the problem: Frank can type a 600-word essay in just 8 minutes. How many words can he type in 60 minutes (1 hour)?
So we know Frank can type 600 words in 8 minutes, we need to find how many words he can type in 60 minutes.
To do that, we will do 60/8, which gives us 7.5. This is how many times 8 minutes goes into 60 minutes. So next, we will do (7.5)(600), which equals 4,500. So Frank can type 4,500 words in 1 hour.
