Incomprehension of fraction to decimal conversion is why 90% of people who say they are bad at math, say they are bad at math

I feel called out. I was in high-school Calculus (11th grade) before I "truly" understood fractions. Like, I honestly somehow managed to make it to Calculus without knowing how to add and subtract fractions without a calculator. Thought I was dumb in math until 9th grade algebra, and didn't start becoming a bit of a math nerd until Calculus
