Let's solve the following calculation:
[tex]\( 11 + 1 + 0.01 + 0.11 + 0.111 \)[/tex]
Step-by-Step Solution:
1. Start by adding the whole numbers:
[tex]\[ 11 + 1 = 12 \][/tex]
2. Next, add the decimal numbers:
[tex]\[ 0.01 + 0.11 + 0.111 \][/tex]
3. Let's add [tex]\( 0.01 \)[/tex] and [tex]\( 0.11 \)[/tex]:
[tex]\[ 0.01 + 0.11 = 0.12 \][/tex]
4. Now, add [tex]\( 0.12 \)[/tex] and [tex]\( 0.111 \)[/tex]:
[tex]\[ 0.12 + 0.111 = 0.231 \][/tex]
5. Finally, add the sum of the whole numbers to the sum of the decimals:
[tex]\[ 12 + 0.231 = 12.231 \][/tex]
So, the final answer is [tex]\( 12.231 \)[/tex].
Thus, the correct answer is:
b. 12.231
