What number is that,which is to 12 increased by three times the number ,as 2 to 9 ?
I do not understand the question.
so, you want x such that
x/(12+3x) = 2/9
Now just crank it out to find x.
To find the number that satisfies the given condition, we can translate the problem into an equation.
Let's assume that the number is represented by the variable "x". According to the problem, the number increased by three times the number (3x) is equivalent to 2 increased by 9 (which can be written as 2 + 9).
So, we can set up the equation: x + 3x = 2 + 9
Simplifying the equation, we have: 4x = 11
To find the value of "x", we can divide both sides of the equation by 4: x = 11/4 or x = 2.75
Therefore, the number that satisfies the given condition is 2.75.
