84 Divided by What Equals 22?
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 84 by to equal 22?
Solving 84 Divided by What Equals 22
Here’s how you would set up this question as an equation:
84
x
=
22
\frac{84}{x} = 22
x 84 = 22
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 84:
84
=
22
∗
x
84 = 22*x
84 = 22 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 22:
84
22
=
x
\frac{84}{22} = x
22 84 = 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
=
3.818
x = 3.818
x = 3.818
