Alright, let's solve these math problems step-by-step:

1. [tex]$2.75 + 0.003 + 0.158$[/tex]
- Add the numbers together:
[tex]\[ 2.75 + 0.003 = 2.753 \][/tex]
[tex]\[ 2.753 + 0.158 = 2.911 \][/tex]
- Therefore, the result is:
[tex]\[ 2.75 + 0.003 + 0.158 = 2.911 \][/tex]

2. [tex]$7.86 - 4.6 + 0.005$[/tex]
- Subtract and add the numbers step-by-step:
[tex]\[ 7.86 - 4.6 = 3.26 \][/tex]
[tex]\[ 3.26 + 0.005 = 3.265 \][/tex]
- Therefore, the result is:
[tex]\[ 7.86 - 4.6 + 0.005 = 3.265 \][/tex]

3. [tex]$7 / 20$[/tex]
- Perform the division:
[tex]\[ 7 \div 20 = 0.35 \][/tex]
- Therefore, the result is:
[tex]\[ 7 / 20 = 0.35 \][/tex]

4. [tex]$(-12) \times 5$[/tex]
- Multiply the numbers:
[tex]\[ (-12) \times 5 = -60 \][/tex]
- Therefore, the result is:
[tex]\[ (-12) \times 5 = -60 \][/tex]

5. [tex]$15 - (-30)$[/tex]
- Subtracting a negative number is equivalent to adding the positive:
[tex]\[ 15 - (-30) = 15 + 30 = 45 \][/tex]
- Therefore, the result is:
[tex]\[ 15 - (-30) = 45 \][/tex]

So, the detailed step-by-step solutions for each of the problems are as follows:

1. [tex]$2.75 + 0.003 + 0.158 = 2.911$[/tex]
2. [tex]$7.86 - 4.6 + 0.005 = 3.265$[/tex]
3. [tex]$7 / 20 = 0.35$[/tex]
4. [tex]$(-12) \times 5 = -60$[/tex]
5. [tex]$15 - (-30) = 45$[/tex]
