Answer 3

we can let "x" be our mystery number

37% of x can be written as 0.37x

so we solve

72 = 0.37x

for x

Answer 4

let me know what you get

Answer 5

Let your "what?" be represented by x.

Then "72 is 37% of what?" becomes "72 is 37% of x."

Convert "37%" to a decimal fraction: "72 is 0.37 of x."

Solve for x.

Answer 6

say "x" is the 100%, and 72 is 37% of that, so \(\begin{array}{ccllll}
amount&\%
\\\hline\\
x&100\\
72&37
\end{array}\implies \cfrac{x}{72}=\cfrac{100}{37}\impliedby \textit{solve for "x"}\)

Answer 7

hey ! take easy use rule of three
\[\frac{ x - 100 }{ 72 - 37 } = 72 x 100 / 37 = 194.5945946\]

Answer 8
