The question is asking how to round the number 83 to the nearest ten. To solve this, we will identify the nearest multiples of ten and determine which one 83 is closest to.
Answer
80
Answer for screen readers
The number 83 rounded to the nearest ten is 80.
Steps to Solve
- Identify the nearest multiples of ten
The tens closest to 83 are 80 and 90.
- Determine the difference to each multiple
Subtract 80 from 83 and 90 from 83:
$$ 83 - 80 = 3 $$
$$ 90 - 83 = 7 $$
- Compare the differences
Now we compare the differences:
- The distance from 83 to 80 is 3.
- The distance from 83 to 90 is 7.
Since 3 is less than 7, we conclude that 83 is closer to 80.
- Round accordingly
Therefore, when rounding 83 to the nearest ten, we round it down to 80.
The number 83 rounded to the nearest ten is 80.
More Information
Rounding is a common practice in mathematics to simplify numbers and make them easier to work with, especially in estimation. It helps in making quick calculations and is widely used in daily life and professions.
Tips
- Rounding up too soon: Some may mistakenly think that since 83 is above the halfway point (85), it should round up. However, rounding must be based on the closest ten.
- Not identifying both nearest multiples: To round correctly, always recognize both the lower and upper ten multiples.
