A sport arena covers 710,430 square feet of ground. A newspaper reported that the arena covets about 700,000 square feet of ground. To what place value was the number rounded?
100,000 square feet [sq]
700,000
100,000
To determine the place value to which the number was rounded, you need to compare the original value of 710,430 square feet to the reported value of 700,000 square feet.
The difference between the two values is:
710,430 - 700,000 = 10,430
The reported value of 700,000 is smaller than the actual value of 710,430, so it was rounded down.
To find the place value to which it was rounded, you need to examine the difference between the two values. The first significant digit that differs between the two numbers is the thousands place (1 in 710,430 and 0 in 700,000).
Therefore, the number was rounded to the nearest thousand, or to the thousands place value.
