23 Divided by What Equals 99?
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 23 by to equal 99?
Solving 23 Divided by What Equals 99
Here’s how you would set up this question as an equation:
23
x
=
99
\frac{23}{x} = 99
x 23 = 99
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 23:
23
=
99
∗
x
23 = 99*x
23 = 99 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 99:
23
99
=
x
\frac{23}{99} = x
99 23 = 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
=
0.232
x = 0.232
x = 0.232
