Аdditionally what is a proportion easy definition?1 : harmonious relation of parts to each other or to the whole : balance, symmetry. 2a : proper or equal share each did her proportion of the work. b : quota, percentage. 3 : the relation of one part to another or to the whole with respect to magnitude, quantity, or degree : ratio.

Addendo: if a:b = c:d then a + c = b + d. Subtrendo: if a:b = c:d then a - c = b - d. Dividendo: if a:b = c:d then a - b:b = c - d:d. Componendo: if a:b = c:d then a + b:b = c + d:d.Solved Examples for Ratio and Proportion Formula.
