Estimation - Solution and Explanation
==================================
Hello! So, lets begin!
"What Is Estimation?"
- It is a rough calculation of the value, number, quantity, or extent of something.
That being said, lets estimate as close as we can for the given expression.
1. We are given the following:
×
We first must multiply the two, however multiply them without their decimal points. Those will be placed in later on.
×
2. Notice, 2.8 has 1 decimal place, and 9.1 also has 1 decimal place. This being said, the final solution will have 2 decimal places.
3. Now, given the following options to choose from, I would say we can roughly estimate the solution to the given expression is B) 27.
