87 Divided by What Equals 6?
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 87 by to equal 6?
Solving 87 Divided by What Equals 6
Here’s how you would set up this question as an equation:
87
x
=
6
\frac{87}{x} = 6
x 87 = 6
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 87:
87
=
6
∗
x
87 = 6*x
87 = 6 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 6:
87
6
=
x
\frac{87}{6} = x
6 87 = 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
=
14.500
x = 14.500
x = 14.500
