There are 16 common ways to prepare eggs, and the Breakfast Booth restaurant prepares eggs in 13 of those ways. To find the percentage, we use the same formula for percentage:
\[
\text{Percentage} = \left( \frac{\text{Number of ways the restaurant prepares eggs}}{\text{Total number of common ways}} \right) \times 100
\]
Substituting the given values:
\[
\text{Percentage} = \left( \frac{13}{16} \right) \times 100
\]
Calculating the fraction:
\[
\frac{13}{16} = 0.8125
\]
Multiplying by 100 to get the percentage:
\[
0.8125 \times 100 = 81.25
\]
Rounding to the nearest tenth:
\[
\approx 81.3\%
\]
\(\boxed{81.3\%}\)
Kenneth did \(\frac{1}{4}\) of his laundry on Sunday and \(\frac{5}{12}\) of his laundry on Monday. To find the total fraction of laundry he did, we need to add these two fractions. First, we find a common denominator for the fractions:
The least common multiple (LCM) of 4 and 12 is 12. Converting the fractions:
\[
\frac{1}{4} = \frac{3}{12}
\]
Now, adding the fractions:
\[
\frac{3}{12} + \frac{5}{12} = \frac{3 + 5}{12} = \frac{8}{12}
\]
Simplifying the fraction:
\[
\frac{8}{12} = \frac{2}{3}
\]
\(\boxed{\frac{2}{3}}\)
