89 Divided by What Equals 8?
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 89 by to equal 8?
Solving 89 Divided by What Equals 8
Here’s how you would set up this question as an equation:
89
x
=
8
\frac{89}{x} = 8
x 89 = 8
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 89:
89
=
8
∗
x
89 = 8*x
89 = 8 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 8:
89
8
=
x
\frac{89}{8} = x
8 89 = 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
=
11.125
x = 11.125
x = 11.125
