cleon would like to estimate the difference between$579 and$85.explain how cleon ccoulduse rounding to make an estimate
Round $579 to $580 or $600
Round $85 to $90 or $100.
If you rounded to $580 and $90 you would get about $670.
If you rounded to $600 and $100 you would get $700.
Cleon can use rounding to make an estimate by rounding the numbers to the nearest tens, hundreds, or thousands. Here's how Cleon can do it:
1. Round $579 to the nearest ten, hundred, or thousand. Let's say Cleon rounds it to the nearest hundred, which is $600. This means that Cleon approximates $579 as $600.
2. Round $85 to the nearest ten, hundred, or thousand. Let's say Cleon rounds it to the nearest ten, which is $90. This means that Cleon approximates $85 as $90.
3. Now, Cleon can calculate the difference between the rounded numbers. In this case, the difference is $600 - $90 = $510.
Therefore, Cleon can estimate that the difference between $579 and $85 is approximately $510 by using rounding.
Cleon can use rounding to make an estimate by rounding the given numbers to the nearest tens, hundreds, or thousands place. Here's how Cleon can proceed:
Step 1: Round $579 to the nearest ten, hundred, or thousand.
To round to the nearest ten, Cleon would need to check the units digit (9) and determine if it is closer to 0 or 10. Since 9 is closer to 10, Cleon can round $579 to $580.
To round to the nearest hundred, Cleon would need to check the tens digit (7) and determine if it is closer to 0 or 10. Since 7 is closer to 10, Cleon can round $579 to $600.
To round to the nearest thousand, Cleon would need to check the hundreds digit (5) and determine if it is closer to 0 or 10. Since 5 is closer to 0, Cleon can round $579 to $1000.
Step 2: Round $85 to the nearest ten, hundred, or thousand.
To round to the nearest ten, Cleon would need to check the units digit (5) and determine if it is closer to 0 or 10. Since 5 is closer to 10, Cleon can round $85 to $90.
To round to the nearest hundred, Cleon would need to check the tens digit (8) and determine if it is closer to 0 or 10. Since 8 is closer to 10, Cleon can round $85 to $100.
To round to the nearest thousand, Cleon would need to check the hundreds digit (0) and determine if it is closer to 0 or 10. Since 0 is closer to 0, Cleon can round $85 to $0.
Step 3: Calculate the difference between the rounded numbers.
Once Cleon has rounded both $579 and $85 to the same place value, he can subtract the rounded value of $85 from the rounded value of $579 to get an estimate of the difference between the two numbers.
For example, if Cleon rounds $579 and $85 to the nearest ten, the rounded values would be $580 and $90. Then, Cleon can calculate the difference by subtracting $90 from $580:
$580 - $90 = $490
So, using rounding, Cleon estimates that the difference between $579 and $85 is approximately $490.
