Equivalent Ratios are similar to Equivalent Fractions. When we simplify two ratios and if they have same value, then they are called as Equivalent Ratios. Equivalent Ratios have different numbers but they represent same relation. For example, 1 : 3 is equivalent to 2 : 6 as they represent same fraction. This calculator calculates the ratios A : B and C : D and finds whether they are equal or not.
