Question

Riley work 5 1/4 hours on Monday 3 3/8 hours on Tuesday and 2 and 5/6 hours on Wednesday he rounded the hours to 5,3,and two before adding them together to get 10 hours did he make a high or low estimate

Answer 1

First, let's convert the mixed numbers to fractions:

5 1/4 = 21/4 = 5.25

3 3/8 = 27/8 = 3.375

2 5/6 = 17/6 = 2.83333

5.25 + 3.375 + 2.83333 = 11.45833333

Therefore he made a low estimate
