To subtract fractions, we need to find a common denominator.
The least common denominator between 12 and 8 is 24.
Now, we can rewrite the fractions with this common denominator:
9/12 = 18/24
3/8 = 9/24
Now, we can subtract these fractions:
18/24 - 9/24 = (18 - 9)/24 = 9/24
So, 9/12 - 3/8 = 9/24
9/12-3/8
