9 Divided by What Equals 58?
Methods
Setting up the problem:
In a problem like this, the “what” means that we’re working with a variable. The most common variable used in math is “x”. So we could say what number, x can we divide 9 by to equal 58?
Solving 9 Divided by What Equals 58
Here’s how you would set up this question as an equation:
9
x
=
58
\frac{9}{x} = 58
x 9 = 58
The goal of the problem is to solve for x. To do this we need to change the equation so that x is alone on one side of the equation.In this case, it can be done in two steps. The first step is to multiply both sides by x to isolate 9:
9
=
58
∗
x
9 = 58*x
9 = 58 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 58:
9
58
=
x
\frac{9}{58} = x
58 9 = x
When we simplify the new equation, we can solve for x. In this example, we will round to the nearest three decimal places if that’s needed.
x
=
0.155
x = 0.155
x = 0.155
