To solve proportions with fractions, first write the two ratios in the same order, then cross multiply to remove the fractions. For example, with 2/3 = x/12, multiply 2 by 12 and 3 by x to get 24 = 3x, so x = 8. You can also simplify the fractions first when that makes the numbers easier to handle, then check the final answer by comparing both ratios. For quick and accurate results, the proportion calculator on SolveProportion lets you enter fractions, find the missing value, and view the exact answer, decimal result, working steps, and verification in one place.
