SOLUTION:
Case: Rounding off numbers to the nearest tens
Rounding a number means adjusting the digits of the number to give an approximation. This value is a simpler representation of the specified number. For example, the population of a city can simply be expressed as 700,000 instead of 698,869. Rounding the numbers makes the calculation easier and makes them easier to remember. However, number rounding only occurs for numbers where the exact value is less important.
Given: 701 + 109
Required: To round off each of the numbers to the nearest tens and then add
Method:
701 + 109.
To the nearest tens, 701 is between 700 and 710. It is closer to 700.
To the nearest tens, 109 is between 100 and 110. It is closer to 110.
Therefore, summing them 700 + 110 = 810.
Final answer:
To the nearest tens, the values are: 700 and 110
The sum is 810
