85 Divided by What Equals 64?
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 64?
Solving 85 Divided by What Equals 64
Here’s how you would set up this question as an equation:
85
x
=
64
\frac{85}{x} = 64
x 85 = 64
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
=
64
∗
x
85 = 64*x
85 = 64 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 64:
85
64
=
x
\frac{85}{64} = x
64 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
=
1.328
x = 1.328
x = 1.328
