Answer
Taylor's time spent singing is given as ( \frac{1}{8} ) and dancing as ( \frac{1}{4} ).
We first convert ( \frac{1}{4} ) to eighths:
( \frac{1}{4} = \frac{2}{8} ).
Now we can add the two fractions:
( \frac{1}{8} + \frac{2}{8} = \frac{3}{8} ).
Thus, Taylor spends ( \frac{3}{8} ) of the show either singing or dancing.

Answer
The total time spent singing and dancing is ( \frac{3}{8} ) of the show. The remainder of the time is backstage, which is 55 minutes.
This means the remaining fraction of time is:
( 1 - \frac{3}{8} = \frac{5}{8} ).
Let ( T ) represent the total time of the show in minutes. Therefore, we can set up the equation:
( \frac{5}{8} T = 55 ).
Step 3

Answer
To find ( T ), multiply both sides by ( \frac{8}{5} ):
( T = 55 \times \frac{8}{5} = 88 ) minutes.

Answer
Now we convert 88 minutes into hours and minutes:
1 hour = 60 minutes
Therefore, 88 minutes is 1 hour and 28 minutes.
Final answer: The duration of the show is 1 hour and 28 minutes.
