Building free math tools- proportions

About

I'm Sheraz Khan. I build free online tools, and Free Proportion Calculator is my latest, a simple and fast calculator that solves proportions step by step. It covers cross multiplication, unit rates, scale factors, percent proportions, direct and inverse variation, and more, with clear worked examples for students and teachers. No sign-up, no cost, just answers with steps. I want to make math less intimidating, one free tool at a time.
