36 Divided by What Equals 72?
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 36 by to equal 72?
Solving 36 Divided by What Equals 72
Here’s how you would set up this question as an equation:
36
x
=
72
\frac{36}{x} = 72
x 36 = 72
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 36:
36
=
72
∗
x
36 = 72*x
36 = 72 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 72:
36
72
=
x
\frac{36}{72} = x
72 36 = 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
=
0.500
x = 0.500
x = 0.500
