81 Divided by What Equals 24?
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 81 by to equal 24?
Solving 81 Divided by What Equals 24
Here’s how you would set up this question as an equation:
81
x
=
24
\frac{81}{x} = 24
x 81 = 24
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 81:
81
=
24
∗
x
81 = 24*x
81 = 24 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 24:
81
24
=
x
\frac{81}{24} = x
24 81 = 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
=
3.375
x = 3.375
x = 3.375
