57 Divided by What Equals 65?
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 57 by to equal 65?
Solving 57 Divided by What Equals 65
Here’s how you would set up this question as an equation:
57
x
=
65
\frac{57}{x} = 65
x 57 = 65
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 57:
57
=
65
∗
x
57 = 65*x
57 = 65 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 65:
57
65
=
x
\frac{57}{65} = x
65 57 = 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
=
0.877
x = 0.877
x = 0.877
