4 Divided by What Equals 66?
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 4 by to equal 66?
Solving 4 Divided by What Equals 66
Here’s how you would set up this question as an equation:
4
x
=
66
\frac{4}{x} = 66
x 4 = 66
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 4:
4
=
66
∗
x
4 = 66*x
4 = 66 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 66:
4
66
=
x
\frac{4}{66} = x
66 4 = 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
