What is 1044.987 rounded to three significant figures

Answer 1

1044.987 rounded to three significant figures is 1040. The digit following the third significant figure ('4') does not require rounding up since it is less than 5.

Step-by-step explanation:

To round the number 1044.987 to three significant figures, we should look at the first three non-zero digits and the digit following them. In the given number, the first three significant digits are '1', '0', and '4'. The fourth digit (following the three significant figures) is a '4', which, being less than 5, does not affect the third significant figure. Thus, 1044.987 rounded to three significant figures is 1040.

When 1044.987 rounded to three significant figures, we can write it as 1040.
