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

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

a = 11 : 4

b = 38

c = 1 for every 6
