Question

Janine spends spends 1/10 hour making the bed, 1/5 hour setting dressed, and 1/2 hour eating breakfast. What fraction of an hour does she spend doing these activities

Answer 1

Answer:

4/5 hour

Step-by-step explanation:

Janine spends spends 1/10 hour making the bed, 1/5 hour setting dressed, and 1/2 hour eating breakfast. Then to find the fraction of the she spent doing this activities, we simply add all the time she spent in doing each activity together and then simplify.

That is;

Time spent in doing activities = time spent in making bed + time spent in setting dress + time spent in eating breakfast.

Time spent in doing activities =  1/10 + 1/5 + 1/2

                                                =$\frac{1 + 2 + 5}{10}$

                                               

                                               =$\frac{8}{10}$

We can further simplify $\frac{8}{10}$ to give us $\frac{4}{5}$  ( when two divide both the numerator and the denominator.

Therefore time spent in doing all the activities is  $\frac{4}{5}$  hour

Answer 2

8/10 or 4/5 of an hour
