What is 2750 rounded to?

Answer 1

The rules when rounding off numbers are as follows :-

1) If the first figure to be discarded is 5 or more, then the previous figure is increased by 1.

Example : 5.1935 = 5.194 (4sf) = 5.19 (3sf) = 5.2 (2sf) = 5 (1sf)

2) Zeros must be kept to show the position of the decimal point or to indicate that zero is a significant figure.

Thus, 2750 is the answer to 4sf and also to 3sf.

2800 is the solution to 2sf and 3000 is the answer to 1 sf.
