Would anyone know how to explain the following formula?
I have 3 values: Valor_Vendido , Valor_Minimo_A_Ser_Vendido and %_Atingida .
Example:
I sold 500 reais and Valor_Minimo_A_Ser_Vendido was to be 1000 reais, so I hit 50% in %_atingida .
Do not need to give me a hand kissed the code in C #, I would just like to know the formula to do the same.
Rule of three. It's more of a mathematical question than a C # problem.
var percentual = (valorVendido * 100) / valorMinino;
Decorating a formula is complicated, because in a few minutes we will surely forget it.
It is better to understand the mechanism, hence we will never forget how to calculate.
Assembly is very simple:
Question
Se 1000 = 100%,
500 = quantos%
Let's build our equation
1000 100
_______ = _______
500 quantos
Asked the question is only to solve the equation.
As it is a simple three-direct rule, we multiply the values in cross, that is, in X,
How many * 1000 = 500 * 100
How many = (500 * 100) / 1000
that would be quantos = (valorVendido * 100) / valorMinino;
How many = 50000/1000
How many = 50%
Remember, a percentage is a ratio of two values (and therefore, one divided by the other) multiplied by 100. Using your example, you soon find out who should be divided by whom; there's only multiplying by 100. That goes for C # or any programming language.
