3/4 is bigger than 3/8. It might seem confusing, but the bigger the denominator, or the number on the bottom, the smaller the fraction. For instance, if you had 4 apples and you ate 1, you could still say that you had most of your apples, since you still have 3/4. However, if you have 8 apples, and you ate 5, then you couldn't say that you have most of them, since you only have 3 of the 8 you started with.
Hope this helps!
