2/4 of an hour is half an hour so 2/4 of an hour is 30 minutes. Hope it helps
Hi there!

We can begin by making each fraction have a common denominator:
If we make each have a common denominator of ab, we get:

Simplify:

Multiply both sides by ab:

Move b to the opposite side:

Factor out b:

Divide by (ac - 1):

Answer:
see below
Step-by-step explanation:
1/12 - 5/6 = -9/12
We need to get a common denominator of 12
1/12 - 5/6*2/2 = -9 /12
1/12 - 10/12 = -9/12
Since the denominators are the same, we can subtract the numerators
1-10 = -9
-9/12 = - 9/12
We can simplify -9/12 by dividing the top and bottom by 3
-9/3 = -3
12 /3 = 4
-9/12 = -3/4
