Hi everyone, I'm Sheraz. I built Free Proportion Calculator because I kept seeing students get stuck on proportions, not because the math is hard, but because most calculators just give an answer with no working shown. So I made a free tool that shows every step. Type in three numbers, leave one blank, and it solves it with cross multiplication, explained clearly. It also covers unit rates, scale factors, percent proportions, direct and inverse variation, and real word problems like recipes and map scales. It's free, no sign-up, and works on mobile and desktop. I built it for students and teachers, and I'd love your feedback. What would make it more useful for you? A practice mode, more worked examples, or something else? Let me know in the comments, I read every one. Thanks for checking it out!
