Answer :
Certainly! Let's break down each of the items and understand the step-by-step solution:
1) [tex]$13.5 + 2 = $[/tex]
- Start with adding the two numbers: 13.5 and 2.
- The result is 15.5.
2) [tex]$8.143 = $[/tex]
- This is already a number and needs no operation.
- The result is 8.143.
3) [tex]$40.5 + 4 = $[/tex]
- Add the two numbers: 40.5 and 4.
- The result is 44.5.
4) [tex]$2642 = $[/tex]
- This is already a number and needs no operation.
- The result is 2642.
5) [tex]$51.7411 = $[/tex]
- This is already a number and needs no operation.
- The result is 51.7411.
6) [tex]$149.1 ÷ 7 = $[/tex]
- Divide 149.1 by 7.
- The result is 21.3.
7) [tex]$30.5 ÷ 5 = $[/tex]
- Divide 30.5 by 5.
- The result is 6.1.
8) [tex]$85.2 ÷ 6 = $[/tex]
- Divide 85.2 by 6.
- The result is approximately 14.2.
9) [tex]$10 ÷ 4 = $[/tex]
- Divide 10 by 4.
- The result is 2.5.
10) [tex]$164.2 ÷ 2 = $[/tex]
- Divide 164.2 by 2.
- The result is 82.1.
These are the step-by-step explanations for each calculation in the list.
