Question
34 × 43 rounded to 30 × 40 this is over estimate or under estimate?
- Over estimate
- Under estimate
- Not estimated
- Estimate
Hint:
Basically Underestimate means 'a guess about the amount, cost, size, etc. of something that is less than the real amount, cost, etc.'
The correct answer is: Under estimate
Step1: 34 rounds to 30.
Step2:43 rounds to 40.
Both numbers used to estimate were less than the actual number.
So, 30 × 40 is an underestimate.
The estimate math definition is a quick guess that is close enough to work with but is not necessarily accurate. Estimating products by rounding numbers to the nearest ten, hundred, thousand etc.
