Problem
23 × 41
Estimate
Solve
Reasonable?
yes
no
Answer: Given the value is 23 and 41.
Now, we will find the product value and estimated value.
First, estimate the given values to nearest tens.
So, the value 23 is roundoff to 20 and 41 is roundoff to 40.
Then the estimate value is , 20 x 40 = 800.
Now, we will find the actual product value.
The values are 23 and 41. Multiply it.
Now, check its reasonable or not.
Yes, its reasonable 943 is approximately equal to 800.
