**$156.87.**Round this to the nearest dollar.

**Step 1**: Locate the ones place.

**$156.87**

**Step 2**: Use the number to the right to determine if you round up or stay the

**$156.87**

**The 8 tells us to round up the 6 to a 7.Step 3**: Rewrite the answer ending in the ones place.

**$157**

**Does our answer make sense? Rounding to the nearest dollar is really just asking, "Is $156.87 closer to $156 or $157? It is only 13 cents away from $157. So it is definitely closer to $157. Therefore, this would be our answer when we round.Example 2: Kyla finished the race in 28.9995**seconds. Round to the nearest secon

**First, let"s use common sense. Is 28.9995 closer to 28 or 29? We know it is closer to 29 seconds. Now let"s show it with our steps.Step 1**:Locate the ones place.

**28**.9995

**Step 2**: Use the number to the right to determine if you round up or stay the same.

**28**.

**9**995

**Notice that the number is above 5, so we round up.Step 3**: Rewrite the answer ending in the ones place.

**About 29 seconds**

**57**.221

**Step 2**: Use the tenths place to help round.

**57**.

**2**21

**Since the number to the right is less than 5, we leave itStep 3**: Write out the rounded answer.

**57 pounds**

**Example 4:19.831**centimeters rounded to the nearest centimeter.
