Press Help me! to imput your ratio. For example, if your ratio is 382 : 230948 and you need to find an equivalent ratio, press help me. It will say "top ratio?" and put in 382. "bottom ratio?" would be 230948. On the right, it would then show you an answer, multiplied by 2, 3, 4, 5, of 6. (answers: 2292:1385688, 1528:923792, 1910:115470, 764:461896, etc.)
My math teacher, when teaching us ratios, and my technology teacher, when showing us coding. Thank you all!
