You can put this solution on YOUR website! Watermelon example:
Use rate as watermelons per day and find the rate for 1 person.
If 13 people pick 112 watermelons in 1 day,
Then 1 person picks 112 watermelons in  days. That is 112 melons per 13 days.
When people work together, their rates are added through simple arithmetic addition. For n count of people to pick watermelons, the rate will be  melons per day.
What is wanted? What is n so that in t=1, the number of watermelons picked is 200. r*t=Q, where Q is count of melons picked, t is days of picking, and r is rate of the workers picking those melons.
In this situation,  , and you want to find n, the number of workers who will pick those 200 melons in that one day.
