Answer:
Step-by-step explanation:
Let's set up a proportion.
He can peel 125 oranges in 5 hours. First, let's find the minutes in 5 hours.
There are 60 minutes in 1 hour, so multiply 60 and 5 (60*5=300). There are 300 minutes in 5 hours.
We don't know how many oranges he can peel in 12 minutes. So we say he can peel x oranges in 12 minutes.
Solve for x by isolating it. x is being divided by 12. The inverse of division is multiplication. Multiply both sides of the proportion by 12.
Rob can peel 5 oranges in 12 minutes.
