Let the number be x
[tex] \rightarrow \: 9x = \frac{1}{3} \\ [/tex]
a second algebraic expression that is different from, but equivalent to the first eexpression
[tex]\rightarrow \: x = \frac{1}{27} \\ [/tex]
Answer:
=> let the unknown number be x
so ,
=> 9x = 1/3 ..i)
=> x = 1/27 ...ii) { it's different but equivalent }
