Ratios are used everywhere, from cooking with your favourite recipes to building housing, here are some common applications of ratios in everyday life: A ratio calculator looks to define the relationship that compares between those two numbers Where are Ratio Calculations Used? If you found the Equivalent Ratio Calculator, you will probably find the following ratio calculators useful:Ī ratio is a direct comparison of one number against another. In our equivalent ratio formula, we can see that by multiplying both the numerator and denominator by the same amount (a) that we maintain the relationship with all equivalent ratio and our initial ratio from which we started the calculation More Good Ratio Calculators We have previously covered the numerator and denominator in the Fractions Calculator, if you are not familiar with the numerator and denominator or simply wish to refresh your memory please review that article and supporting calculator before proceeding. This can only be achieved via multiplication of division.Īs equivalent ratios have the same value there is technically no equivalent ratio formula but the following equivalent ratio formula will help you with the manual math calculations. The important point to remember is that equivalent literally means equal, so what you are calculating is the same ratio expressed in different quantities. Although the quantities vary, the ratio of the numerator and denominator are the same (both can be divided by 2 in this instance). for example, if you have 10 sweets to share with 4 friends, this is the same and having 5 sweets to share with 2 friends in ratio terms. When calculating equivalent ratios it is important to understand that mathematically, you are expressing the same relationship, simply in different amounts. How to Manually Calculate Equivalent Ratios This way you can check your answers and build up your confidence. If you are still working on your mental arithmetic and manual ratio calculations, we suggest that you first enter the ratio into the calculator to see the results, then complete the manual math using the equivalent ratio formula. That great, understand math formula and calculations is important, particularly ratio math as ratios are used in a significant number of business calculations, finance calculations and general day to day calculations, for example: miles per hour, your BMI, the amount of money your share or sweets you share with friends, these are all good examples of ratios. This is useful for quick math but you may wish to calculate equivalent ratio manually.
