Math Problem Statement
Solution
The question asks to arrange the following numbers in descending order: 3, 8, 2.1, -0.12, √5.
To begin with:
- The number 8 is the largest.
- √5 (approximately 2.236) comes next.
- 3 is slightly smaller than √5.
- 2.1 follows.
- -0.12 is the smallest value, as it's negative.
So, the numbers in descending order are:
8, √5, 3, 2.1, -0.12
Would you like more explanation on any of these steps or have any other questions?
Here are some additional related questions:
- How do we estimate the square root of numbers like √5 without a calculator?
- What is the significance of negative numbers in ordering?
- Can we use approximation for irrational numbers like √5 when comparing them?
- How does ordering help in real-world scenarios like budgeting or ranking?
- What are the differences between descending and ascending order?
Tip: When comparing square roots or irrational numbers, try using approximations to make the comparison easier.
