The correct option for rounding 3.2350 to two decimal places is c. 3.24. When rounding numbers, you look at the number immediately to the right of the place to which you are rounding.

Check Your Learning shows the process of rounding to a certain number of significant figures:
- (a) 0.424 would be rounded to 0.42 because the third figure (4) is less than 5.
- (b) 0.0038661 would be rounded to 0.00387 because the sixth figure (6) is greater than 5.
- (c) 421.25 would be rounded to 421.3 because the last figure (5) leads to rounding up the previous figure.
- (d) 28,683.5 would be rounded to 28,684 because the number after the decimal (5) causes the last digit before the decimal to increase by one.
