Help please it’s homework
Fudgin [204]

Answer:

10. 1/9

11. 1 1/6

12. 1/8

Step-by-step explanation:

10.

He spent 2/3 of 1/6 of the day.

In math, "of" means multiplication, so 2/3 of 1/6 means 2/3 * 1/6.

2/3 * 1/6 = 2/18 = 1/9

He spent 1/9 of the day adding mulch.

11.

He spent 2/3 of 1 3/4 hours.

In math, "of" means multiplication, so 2/3 of 1 3/4 means 2/3 * 1 3/4.

2/3 * 1 3/4 = 2/3 * 7/4 = 14/12 = 7/6 = 1 1/6

He spent 1 1/6 hours working on the project.

12.

She planted 1/6 of 3/4 of the area.

In math, "of" means multiplication, so 1/6 of 3/4 means 1/6 * 3/4.

1/6 * 3/4 = 3/24 = 1/8

She planted carrots in 1/8 of the garden.
