Dude bro. I absolutely use fractions everyday. It's useful for shopping, figuring out the odds on a poker hand, organizing events, etc. If you are good at math you will absolutely constantly be using fractions because they are so useful. I am also an Electrical Engineer, so yeah... even more fraction use there. We learned tons of useless BS in school, but fractions isn't one of them. Try cursive handwriting. That one is a complete waste of time because no one will ever be able to read your cursive.
