5 Divided by What Equals 82?
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 5 by to equal 82?
Solving 5 Divided by What Equals 82
Here’s how you would set up this question as an equation:
5
x
=
82
\frac{5}{x} = 82
x 5 = 82
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 5:
5
=
82
∗
x
5 = 82*x
5 = 82 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 82:
5
82
=
x
\frac{5}{82} = x
82 5 = 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
=
0.061
x = 0.061
x = 0.061
