15 Divided by What Equals 73?
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 15 by to equal 73?
Solving 15 Divided by What Equals 73
Here’s how you would set up this question as an equation:
15
x
=
73
\frac{15}{x} = 73
x 15 = 73
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 15:
15
=
73
∗
x
15 = 73*x
15 = 73 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 73:
15
73
=
x
\frac{15}{73} = x
73 15 = 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
=
0.205
x = 0.205
x = 0.205
