Answer:
Step-by-step explanation:
Nora worked in her yard for 2 hours. She mowed for 45 minutes. We would convert the 45 minutes to hours.
60 minutes = 1 hour
45 minutes = 45/60 = 3/4 hours
She raked for 33 minutes. Converting 33 minutes to hours,
33 minutes = 33/60 = 11/20
She weeded the garden for the rest of the time.
Time spent on weeding the garden = total time spent in the garden - sum of the time spent on mowing and raking.
Time spent on weeding = 2 - (3/4+11/20) = 2 - 26/20
= 14/20 = 0.7 hours
The percentage of Nora's time working in her yard that was spent weeding the garden will become
0.7/2 × 100
= 35%
