To solve the expression \( \frac{3}{11} + \frac{2}{7} \cdot 1 \cdot \frac{5}{1843} \cdot \frac{775}{7743} \cdot \frac{1}{18} \), let's break this down step-by-step.
First, compute the multiplication part:
-
Start with \( \frac{2}{7} \cdot 1 = \frac{2}{7} \).
-
Next, multiply by \( \frac{5}{1843} \): \[ \frac{2}{7} \cdot \frac{5}{1843} = \frac{10}{7 \cdot 1843} \] \( 7 \cdot 1843 = 12901 \), so: \[ \frac{10}{12901} \]
-
Then, multiply by \( \frac{775}{7743} \): \[ \frac{10}{12901} \cdot \frac{775}{7743} = \frac{7750}{12901 \cdot 7743} \]
To compute \( 12901 \cdot 7743 \), we just keep it as is for now: \[ 12901 \cdot 7743 \]
-
Finally, multiply by \( \frac{1}{18} \): \[ \frac{7750}{12901 \cdot 7743} \cdot \frac{1}{18} = \frac{7750}{18 \cdot 12901 \cdot 7743} \]
Now we need to add this result to \( \frac{3}{11} \).
To add \( \frac{3}{11} \) and \( \frac{7750}{18 \cdot 12901 \cdot 7743} \), we convert them to a common denominator. The common denominator will be \( 11 \cdot 18 \cdot 12901 \cdot 7743 \).
Calculate \( \frac{3}{11} \) in terms of the common denominator: \[ \frac{3 \cdot 18 \cdot 12901 \cdot 7743}{11 \cdot 18 \cdot 12901 \cdot 7743} \]
And for \( \frac{7750}{18 \cdot 12901 \cdot 7743} \): \[ \frac{7750 \cdot 11}{11 \cdot 18 \cdot 12901 \cdot 7743} \]
Now we can add these two fractions: \[ \frac{3 \cdot 18 \cdot 12901 \cdot 7743 + 7750 \cdot 11}{11 \cdot 18 \cdot 12901 \cdot 7743} \]
After performing the required calculations on the numerator, you can simplify if necessary.
However, the resulting expression can be quite large and cumbersome. If you need a numerical approximation or specific values, you'd typically want to use a calculator or computational tool at this point.
Let’s summarize:
- Result of \( \frac{2}{7} \cdot \frac{5}{1843} \cdot \frac{775}{7743} \cdot \frac{1}{18} = \frac{7750}{18 \cdot 12901 \cdot 7743} \)
- Add \( \frac{3}{11} \).
If you provide or require specific simplifications or a decimal approximation, let me know!
