Question

Kylie works part-time at a greenhouse. She spends 7 hours a week watering plants and 9 hours a week transplanting seedlings. She also spends 4 hours a week filling invoices. What percent of her time is spent watering plants?

Answer 1

Add up the number of hours she works (7+4+9)

Divide the number of hours spent watering plants (7) by this number

Multiply this by 100 to get the percent of her time that she spends watering plants.

My work:
7+4+9= 20
20/7=2.85714286
2.85714286*100=285.714286

Answer 2

She spends 35% of her time watering plants.

Hope that helped!
