83 Divided by What Equals 18?
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 83 by to equal 18?
Solving 83 Divided by What Equals 18
Here’s how you would set up this question as an equation:
83
x
=
18
\frac{83}{x} = 18
x 83 = 18
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 83:
83
=
18
∗
x
83 = 18*x
83 = 18 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 18:
83
18
=
x
\frac{83}{18} = x
18 83 = 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
=
4.611
x = 4.611
x = 4.611
