I ask this QU. so it is stupid i have to answer it :(
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
46.78-18.55 and estimate each sum or difference = 28.23
I'm not sure about the question your asking but I'm pretty sure it's 58.92
7.8+31.39+6.95
5.13+2.28=7.41
1,400

That equals 16.7 which would be between 15 and 18.
The range of a single number - with or without a decimal - is zero.
Round down and round up. The answer will be between 20 (7 + 13) and 22 (8 + 14)
