Before school, Janine spends 1/10 hour making her bed, 1/5 hour getting dress, and 1/2 hour eating breakfast. What fraction of an hour does she spend doing these activities?

4/5

Step-by-step explanation:

This is a long-winded way to ask you the sum of the three fractions:

1/10 + 1/5 + 1/2

= 1/10 + 2/10 + 5/10 = (1 + 2 + 5) / 10 = 8/10

= 4/5

Janine spends 4/5 hour doing morning activities.
