1.6 hours

Step-by-step explanation:

Leah practices dance for 2 hours each week.

Her younger sister Sonia practices dance for 0.8 the amount of time Leah practices.

The time of practice by Sonia = 0.8 of 2 hours

= 0.8 * 2

= 1.6 hours

Converting 1.6 hours to hours and minute.

1 hour (0.6 * 60) 36 minutes

Sonia practices dance for 1 hour 36 minutes each week.
