To add the fractions \( \frac{12}{1} + \frac{38}{1} \), you can first rewrite \( 12 \) and \( 38 \) as fractions:
\[ \frac{12}{1} + \frac{38}{1} = \frac{12 + 38}{1} \]
Now, simply add the numerators:
\[ \frac{50}{1} = 50 \]
Since \( 50 \) is not one of the options, it appears that the question intends for you to add the whole number \( 12 \) (which may have been misrepresented). If the fraction being added is less than one, for example, if it were \( \frac{3}{8} \) instead of \( 38 \) after realizing there's likely a typographical error, you could also present it as:
\[ 12 + \frac{3}{8} \]
For the case of \( \frac{12}{1} + \frac{3}{8} \):
Converting \( 12 \) to have the same denominator as \( \frac{3}{8} \):
\[ 12 = \frac{96}{8} \]
Now perform the addition:
\[ \frac{96}{8} + \frac{3}{8} = \frac{99}{8} \]
But if it was \( \frac{3}{8} \), it'll lead us back to the original representation in simplest fraction form.
Given the options:
- \( 4/10 \) which simplifies to \( 2/5 \)
- \( 1/2 \)
- \( 2/5 \)
- \( 78 \)
The approach confirmed seems to not fit directly to options.
The result of \( 12 + \frac{38}{1} \) does not align with listed answer choices. More context on those fractions would help.
However, if just performing:
Ultimately:
The choices are confusing as they do not coincide logically or mathematically with how to operate under rational interpretation of typical fractional representation.
It would be a good practice to clarify fractions and intended sums.
