The data wasn't provided to answer this question. The range in math is the highest number minus the lowest number. For example 30,20,10,5 the range would be 30 minus 5 which equals 25.
7.8+31.39+6.95
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
A reasonable estimate of the sum of 78 and 119 is 197.
One estimate is 800 although there is really no need t estimate such a simple sum: it is 778.
To estimate the sum of 3.89, 42.71, and 12.32, we can round each number to the nearest whole number. This gives us 4, 43, and 12. Adding these rounded numbers gives us an estimated sum of 59. However, it's important to note that this is just an estimation and the actual sum will be slightly higher than this.
The range of a single number - with or without a decimal - is zero.

The largest value is 17.563 The smallest is 2.31 So the range is 17.563 - 2.31 = 15.253
Round the highest and lowest numbers. 25 - 5 = 20
Round the highest and lowest numbers. 25 - 5 = 20
The sum is 2.05 and you don;t need to estimate such a simple sum!
That equals 16.7 which would be between 15 and 18.
