73 Divided by What Equals 31?
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 73 by to equal 31?
Solving 73 Divided by What Equals 31
Here’s how you would set up this question as an equation:
73
x
=
31
\frac{73}{x} = 31
x 73 = 31
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 73:
73
=
31
∗
x
73 = 31*x
73 = 31 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 31:
73
31
=
x
\frac{73}{31} = x
31 73 = 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
=
2.355
x = 2.355
x = 2.355
