Divide both numbers by their greatest common divisor. 16:24 - the common divisor is 8, giving 2:3. If the numbers are not whole, the calculator writes the ratio as 1:x.
In the proportion A:B = C:D the products of the outer and inner terms are equal: A × D = B × C, so D = B × C / A. For 16:24 = 20:D we get D = 24 × 20 / 16 = 30.
Add the parts (3 + 2 = 5), divide the amount by that and multiply by each part. 1000 in the ratio 3:2 is 600 and 400. That is how profit is split between partners or ingredients in a recipe.
