Step-by-step Solution
Let's analyze the equations step by step.
1. **First Equation:**
\[
\frac{1}{3} + \frac{2}{5}
\]
To add these fractions, we need a common denominator. The least common multiple of 3 and 5 is 15.
Converting each fraction:
\[
\frac{1}{3} = \frac{5}{15} \quad \text{and} \quad \frac{2}{5} = \frac{6}{15}
\]
Now we can add them:
\[
\frac{5}{15} + \frac{6}{15} = \frac{5 + 6}{15} = \frac{11}{15}
\]
So, the first equation simplifies to:
\[
\frac{1}{3} + \frac{2}{5} = \frac{11}{15}
\]
2. **Second Equation:**
\[
\frac{1}{2} + \frac{5}{10}
\]
Here, we can see that \(\frac{5}{10}\) simplifies to \(\frac{1}{2}\).
Therefore:
\[
\frac{1}{2} + \frac{5}{10} = \frac{1}{2} + \frac{1}{2} = 1
\]
Now, let's fill in the blanks in the original equations:
- For the first equation:
- \(L = 11\)
- The denominator for both fractions is \(15\).
- The numerator for the second fraction is \(6\).
- The final result is \(11\).
- For the second equation:
- The first fraction has a numerator of \(5\) and a denominator of \(10\).
- The final result is \(1\).
Thus, we can summarize the filled-in values:
\[
\left. \begin{array} { l } { \frac { 1 } { 3 } + \frac { 2 } { 5 } = \frac { ( 11 ) ( 1 ) } { ( 1 ) ( 3 ) } + \frac { ( 6 ) ( 2 ) } { ( 1 ) ( 5 ) } = \frac { 5 } { 15 } + \frac { 6 } { 15 } = \frac { 11 } { 15 } } \\ { \frac { 1 } { 2 } + \frac { 5 } { 10 } = \frac { ( 5 ) ( 1 ) } { ( 1 ) ( 2 ) } + \frac { 5 } { 10 } = \frac { 5 } { 10 } + \frac { 5 } { 10 } = 1 } \end{array} \right.
\]
Quick Answer
\[
\left. \begin{array} { l } { \frac { 1 } { 3 } + \frac { 2 } { 5 } = \frac { 11 } { 15 } } \\ { \frac { 1 } { 2 } + \frac { 5 } { 10 } = 1 } \end{array} \right.
