That equals 16.7 which would be between 15 and 18.

71 + 847 = 918 165 + 72 = 237 192 + 192 = 384

First, round the highest place value of each number: 400+200+700=1300 Second, round the second highest place value of each number: 390+190+740=1320 The range to estimate the sum is 1300 to 1320. The actual sum is 1321, which higher than the range. However, the actual sum may lie within the obtained range. LEF
I'm not sure about the question your asking but I'm pretty sure it's 58.92
between 20 and 30
I ask this QU. so it is stupid i have to answer it :(

Notice that each of the three numbers is rather close to 9,000. The estimated sum is 27,000.

46.78-18.55 and estimate each sum or difference = 28.23
71 + 847 = 918 165 + 72 = 237 192 + 192 = 384
