Give an example of real life real problems of the following and solve them?

Person A and Person B work on a project. Person A does three times as much work as Person B. What is the ratio of the amount of work person B does and what is the percentage? What is the ratio of the whole amount of work each does, and the percentage?

Person B does 1/3 of the work person A does, so 33.33%

Of the whole amount of work (four shares), person A does 3/4 and person B does 1/4. Person A does 75% of the work, person B does 25%.

To convert a ratio to a percentage just multiply by a hundred.
