85 Divided by What Equals 57?
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 85 by to equal 57?
Solving 85 Divided by What Equals 57
Here’s how you would set up this question as an equation:
85
x
=
57
\frac{85}{x} = 57
x 85 = 57
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 85:
85
=
57
∗
x
85 = 57*x
85 = 57 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 57:
85
57
=
x
\frac{85}{57} = x
57 85 = 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
=
1.491
x = 1.491
x = 1.491
