83 Divided by What Equals 20?
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 20?
Solving 83 Divided by What Equals 20
Here’s how you would set up this question as an equation:
83
x
=
20
\frac{83}{x} = 20
x 83 = 20
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
=
20
∗
x
83 = 20*x
83 = 20 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 20:
83
20
=
x
\frac{83}{20} = x
20 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
=
4.150
x = 4.150
x = 4.150
