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
