Round off 5.373 to two significant figure
5.4
To round off 5.373 to two significant figures, we need to consider the digits before and after the decimal point.
Since the number has only one digit before the decimal point (5), the first significant figure is 5. The second significant figure will be the first non-zero digit after 5, which is 3.
To round off to two significant figures, we need to evaluate the digit after the second significant figure (the 3 in this case). If it is 5 or greater, we round up. If it is less than 5, we round down.
The digit after the second significant figure is 7, which is greater than 5. Therefore, we round up the second significant figure (3) to the next highest value, which is 4.
Hence, rounding off 5.373 to two significant figures yields 5.4.
