Answer:

approx. 1/2

part B: 11/24

1/24, explanation in step by step

Step-by-step explanation:

10 /12 is close to 1

3/8 is close to 1/2

Part B:

10/12 - 3/8

10/12 = 20 /24

3/8 = 9/24

20/24 - 9/24 = 11/24

1-1/2=1/2

Part C:

1/2 - 11/24 = 12/24 - 11/24 = 1/24

I think my answer is reasonable because when I subtracted my answer from my estimate, I got a number very close to 0
