round off to two significant figures the number is 3.75


In rounding significant figures, when an integer contains more digits than are significant, the last significant digit has an overline to indicate that it is the last significant digit.

When rounding significant figures the standard rules of rounding numbers apply, except that non-significant digits to the left of the decimal are replaced with zeros.

Rounds down if the next digit is less than 5 and rounds up when the next digit is greater than or equal to 5.

3.75 contains 3 significant figures and 2 decimals. 3.75 rounded to 2 significant figures is 3.8.
