When rounding numbers, the decimal point is used as a guide. The number to the right of the decimal point determines the value of the digit to the left of the decimal point. When rounding to the nearest tenth, the digit to the right of the decimal point is rounded up if it is 5 or higher, and rounded down if it is 4 or lower. Therefore, when rounding 1.32 to the nearest tenth, the value of the digit to the right of the decimal point will determine the value of the digit to the left of the decimal point.

## Rounding Rules

The rules for rounding to the nearest tenth are simple: if the digit to the right of the decimal point is 5 or higher, then the digit to the left of the decimal point is rounded up; if the digit to the right of the decimal point is 4 or lower, then the digit to the left of the decimal point is rounded down. In the case of 1.32, the digit to the right of the decimal point is 2, which is lower than 5. Therefore, the digit to the left of the decimal point is rounded down.

## Rounding 1.32 to the Nearest Tenth

To round 1.32 to the nearest tenth, the digit to the left of the decimal point is decreased by one. Therefore, 1.32 rounded to the nearest tenth is 1.3. This is because when rounding to the nearest tenth, the digit to the right of the decimal point is rounded down if it is 4 or lower. In this case, the digit to the right of the decimal point is 2, which is lower than 5. Therefore, the digit to the left of the decimal point is decreased by one.

## Examples of Other Rounding to the Nearest Tenth

For other examples of rounding to the nearest tenth, consider the following numbers: 3.45, 5.87, and 7.29. For 3.45, the digit to the right of the decimal point is 5, which is higher than 4. Therefore, the digit to the left of the decimal point is rounded up, and 3.45 rounded to the nearest tenth is 3.5. For 5.87, the digit to the right of the decimal point is 7, which is higher than 4. Therefore, the digit to the left of the decimal point is rounded up, and 5.87 rounded to the nearest tenth is 5.9. For 7.29, the digit to the right of the decimal point is 9, which is higher than 4. Therefore, the digit to the left of the decimal point is rounded up, and 7.29 rounded to the nearest tenth is 7.3.

In conclusion, when rounding to the nearest tenth, the digit to the right of the decimal point determines the value of the digit to the left of the decimal point. If the digit to the right of the decimal point is 5 or higher, then the digit to the left of the decimal point is rounded up; if the digit to the right of the decimal point is 4 or lower, then the digit to the left of the decimal point is rounded down. Therefore, 1.32 rounded to the nearest tenth is 1.3.
