Respuesta :

let's say the number is "x".


so "x" was really large, and it went kaput, down to 81, since it was 100%, then it decreased by 95%, so 95% + 5% = 100%, its new size is 5%, and we know that is 81.


if we take 81 to be 5%, what is "x" anyway?


[tex] \bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
81&5\\
x&100
\end{array}\implies \cfrac{81}{x}=\cfrac{5}{100}\implies \cfrac{81\cdot 100}{5}=x\implies 1620=x [/tex]

The number is 1620 which is decreased by 95%, and becomes 81 the answer is 1620.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

Let x be the number:

Then,

x is decreased by 95% and becomes 81.

(100-95)% of x = 81

5% of x = 81

0.05x = 81

x = 81/0.05

x = 1620

Thus, the number is 1620 which is decreased by 95%, and becomes 81 the answer is 1620.
