Step-by-step solution for: Round to the nearest cent worksheet
Let's solve this step-by-step based on the worksheet titled "Rounding Money". The goal is to round each amount to the nearest cent, dime, and dollar.
We’ll go through the rules for rounding:
---
1. To the nearest cent (hundredths place):
- Look at the thousandths digit (3rd decimal).
- If it’s 5 or more, round up the hundredths digit.
- If less than 5, keep the hundredths digit as is.
2. To the nearest dime (tenths place):
- Look at the hundredths digit (2nd decimal).
- If it’s 5 or more, round up the tenths digit.
- If less than 5, keep the tenths digit as is.
- Then drop all digits after the tenths place.
3. To the nearest dollar (ones place):
- Look at the tenths digit (1st decimal).
- If it’s 5 or more, round up the dollar amount.
- If less than 5, keep the dollar amount as is.
- Drop all decimal parts.

Now let’s solve each problem.

🔹 Rounding Rules:
1. To the nearest cent (hundredths place):
- Look at the thousandths digit (3rd decimal).
- If it’s 5 or more, round up the hundredths digit.
- If less than 5, keep the hundredths digit as is.
2. To the nearest dime (tenths place):
- Look at the hundredths digit (2nd decimal).
- If it’s 5 or more, round up the tenths digit.
- If less than 5, keep the tenths digit as is.
- Then drop all digits after the tenths place.
3. To the nearest dollar (ones place):
- Look at the tenths digit (1st decimal).
- If it’s 5 or more, round up the dollar amount.
- If less than 5, keep the dollar amount as is.
- Drop all decimal parts.
