Mixed Rounding Worksheet for practicing rounding numbers to the nearest thousand, hundred, ten, or unit, with an example and 21 exercises.

To solve the problems in the "Mixed Rounding Worksheet," we need to round each number to the accuracy of the underlined digit. Here's how to approach each problem step by step:

Steps for Rounding:

1. Identify the underlined digit.
2. Look at the digit immediately to the right of the underlined digit.
- If this digit is 5 or greater, round up the underlined digit by 1.
- If this digit is less than 5, keep the underlined digit as it is.
3. Replace all digits to the right of the underlined digit with zeros (for whole numbers) or simply drop them (for decimals).

Solutions:

#### 1. \( \underline{3}5,832 \)
- Underlined digit: 3
- Digit to the right: 5
- Since 5 is equal to 5, round up the 3 to 4.
- Result: 40,000

#### 2. \( 19,\underline{0}88 \)
- Underlined digit: 0
- Digit to the right: 8
- Since 8 is greater than 5, round up the 0 to 1.
- Result: 19,100

#### 3. \( \underline{3},631 \)
- Underlined digit: 3
- Digit to the right: 6
- Since 6 is greater than 5, round up the 3 to 4.

#### 4. \( 11,\underline{9}11 \)
- Underlined digit: 9
- Digit to the right: 1
- Since 1 is less than 5, keep the 9 as it is.
- Result: 11,900

#### 5. \( \underline{8}7,087 \)
