For this case we are asked to find a number that when multiplied by "9" of result "35", then we propose an equation with a variable, in which we must find the value of said variable, which represents the number that must be multiplied for 9.
We have to:
x: Represents the number multiplied by "9"
So:
![x * 9 = 35](https://tex.z-dn.net/?f=x%20%2A%209%20%3D%2035)
We must clear the variable "x", for it we divide between "9" on both sides of the equation:
![\frac {9x} {9} = \frac {35} {9}\\x = \frac {35} {9}\\x = 3.888888889](https://tex.z-dn.net/?f=%5Cfrac%20%7B9x%7D%20%7B9%7D%20%3D%20%5Cfrac%20%7B35%7D%20%7B9%7D%5C%5Cx%20%3D%20%5Cfrac%20%7B35%7D%20%7B9%7D%5C%5Cx%20%3D%203.888888889)
If we round with two decimals:
![x = 3.89](https://tex.z-dn.net/?f=x%20%3D%203.89)
Thus, the number that is multiplied by 9, to obtain 35 is ![x = 3.888888889](https://tex.z-dn.net/?f=x%20%3D%203.888888889)
Answer:
![x = 3.888888889](https://tex.z-dn.net/?f=x%20%3D%203.888888889)
