17 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 17 by to equal 8?
Solving 17 Divided by What Equals 8
Here’s how you would set up this question as an equation:
17
x
=
8
\frac{17}{x} = 8
x 17 = 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 17:
17
=
8
∗
x
17 = 8*x
17 = 8 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 8:
17
8
=
x
\frac{17}{8} = x
8 17 = 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
=
2.125
x = 2.125
x = 2.125
