Problem Solving: Using Proportions?

Question

Write a proportion to show how many days a week you exercise. How many in 28 days? Estimate to base your amount of exercising

Answer 1

For example if you exercise 5 days out of the week, then a proportion to show how many days a week you exercise would be 5/7. Or you could say 19/28 days. A proportion is just a fraction, where the denominator is the total sum. I don't understand the last part of your problem though.
