Question 912164: Estimate each of the following by estimating each mixed number as a whole number or as a mixed number where the fractional part is 1/2 and by estimating each fraction as 0, 1/2, or 1. Then carry out any computations that are indicated.
43/100 + 1/10 - 11/1000
7 29/60 + 10 12/13 + 24 2/17
24 divided 7 8/9
76 3/14 + 23 9/20
16 1/5 divided by 2 1/11 + 25 9/10 - 4 11/23

Problems should be posted one at a time. However, since I don't see others posted or abused by you, consider that as "information". Next time, please adhere to the rules. Otherwise, tutors may skip questions from you.
43/100 + 1/10 - 11/1000 = 430/1000 + 100/1000 -11/1000 = 530/1000 - 11/1000 = 519/1000
7 29/60 + 10 12/13 + 24 2/17 = 7 + 10 + 24 = 41 + ( 6409/13260 + 12240/13260 + 1560/13260) = 41 + 20209/13360 = 41 + 1 = 42.51265
24 divided 7 8/9 = approx. 24/3 so you know your answer is near 8. 24 / = 24 * = = 3.04225
76 3/14 + 23 9/20 = 76+23=99 + (+) = 99= 99.6643
16 1/5 divided by 2 1/11 + 25 9/10 - 4 11/23 (I'm assuming that 16.2 is the numerator and the others are the denominator.)
2+25-4 = 23+(+-) = 23
