How to estimate a number??? with example
Answers
Answer:
The general rule for estimating is to look at the digit to the right of the digit you want to estimate. Estimating or rounding to the nearest whole number means looking at the digit to the right of the decimal. If you see a digit greater than 5, round up, and if it's less than 5, round down.Estimating a Difference. A quick way to estimate the difference between two numbers is to round each number and then subtract the rounded numbers.
To find a value that is close enough to the right answer, usually with some thought or calculation involved. Example: Alex estimated there were 10,000 sunflowers in the field by counting one row then multiplying by the number of rows.
Example:
550 + 298: 298 is nearly 300 so an estimate is 550+300 = 850.
550 + 248: 50+48 is nearly 100 so an estimate is 500+200 +100 = 800.
