I have two numbers, one of them is fixed (1700) and one will always be alternating between 0 and 1700, I want to calculate the percentage of that number that is alternating, for example, when the number is 1071 the percentage is equal to 63%, when 1700 is equal to 100%!
$NumeroFixo = 1700
$Alternado = 1071
$Porcentagem = 63%
How can I do that ?

It’s more of a math problem than PHP.
Just make a rule of three and act in the code.
The rule of three is simple, I believe you already know, but I’ll leave logic as a demonstration
Se 1700 é 100%, quantos % é 1071? 1700 --- 100 1071 --- x Multiplica-se as diagonais e tem-se: 1700x = 1071*100; -> 1700x = 107100; -> x = 107100 / 1700; -> x = 63
Now just swap these values by variable names and represent the expression in code.
$Porcentagem = ($Alternado * 100) / $NumeroFixo;
ah tendi, Thank you!

Is confused:
1071 a porcentagem seja igual a 63%, quando for 1700 seja igual a 100%how so?– novic
1071 is 63% of 1700!

@Fox Is that example using similar numbers induces error.
