To round the number 3.6432 to the nearest hundredth, we look at the third decimal place (the thousandths place) to determine whether to round up or down.
In 3.6432:
- The hundredths place is 4 (the second digit after the decimal).
- The thousandths place is 3 (the third digit after the decimal).
Since 3 is less than 5, we do not round up.
Thus, 3.6432 rounded to the nearest hundredth is 3.64.
