QuestionEstimate if $22.8 \times 4.7 = 107.16$ is reasonable. Respond with yes or no, and give a better estimate if no.

Studdy Solution

STEP 1

Assumptions1. The multiplication operation is correctly performed. . Estimation involves rounding the numbers to the nearest whole number or to a number that is easy to work with for mental calculations.

STEP 2

First, we need to estimate the numbers given in the problem. We can round $22.8$ to $20$ and $4.7$ to $5$ for easier calculations.
$Estimated\, product =20 \\times5$

STEP 3

Calculate the estimated product.
$Estimated\, product =20 \\times5 =100$

STEP 4

Now that we have the estimated product, we can compare this with the given answer in the problem, which is $107.16$ .

STEP 5

Given that our estimated product is $100$ and the actual answer is $107.16$ , we can see that these two numbers are reasonably close. Therefore, the answer is reasonable.
The answer is yes, the given answer is reasonable.
