20
Answer for screen readers
The rounded number is ( 20 ).
Steps to Solve
- Identify the number and its place values
We need to consider the number 17, which has two digits: 1 (the tens place) and 7 (the units place).
- Look at the units place digit
The next step is to look at the digit in the units place, which is 7.
- Apply rounding rules
According to standard rounding rules, if the digit in the units place is 5 or higher, we round up. Since 7 is higher than 5, we will round up.
- Determine the rounded value
Since we round up from 17, we add 1 to the digit in the tens place (1) and make the units place 0. Therefore, rounding 17 up gives us 20.
The rounded number is ( 20 ).
More Information
Rounding is a common mathematical technique used to simplify numbers. When rounding to the nearest ten, you only focus on the last digit (units place) to decide if you increase (round up) or keep the same (round down) the tens place digit.
Tips
- A common mistake is not checking the units digit properly. Always ensure to observe if it’s 5 or above to round up, and below 5 to round down.
- Misunderstanding the place value can also lead to errors. Remember that the tens place affects the number we round to.
