Priya spent 1/2 of the day hiking. She was lost 5/6 ​​of the time that she was hiking. What fraction of the day was Priya lost
Vadim26 [7]

Answer:

\frac{5}{12} fraction of the day was Priya lost

Step-by-step explanation:

As per the statement:

Priya spent 1/2 of the day hiking.

⇒She spent for hiking = 1/2 of the day.

It is also given that:

She was lost 5/6 ​​of the time that she was hiking.

⇒\text{She lost} = \frac{5}{6} \times \text{She was hiking}

Substitute the given values we have;

\text{She lost} = \frac{5}{6} \times \frac{1}{2} = \frac{5}{12} of the day

therefore, \frac{5}{12} fraction of the day was Priya lost
