Awaitress works 1.75 hours less in the afternoon than in the evening. if she works 5   1/8hours in the afternoon, how many hours does she work in the evening?

If the waitress works x hours in the evening, according to the problem, she works x-1.75 hours in the afternoon. We have given that she works 5.125 hours in the afternoon, which is x-1.75=5.125. BY solving this equation, we find unknown x, which is equal to 6.87 hours and it is the answer to the problem.

These are the multiples of 15 but what you are probably asking or what are the factors of 15
