18 Divided by What Equals 29?
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 18 by to equal 29?
Solving 18 Divided by What Equals 29
Here’s how you would set up this question as an equation:
18
x
=
29
\frac{18}{x} = 29
x 18 = 29
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 18:
18
=
29
∗
x
18 = 29*x
18 = 29 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 29:
18
29
=
x
\frac{18}{29} = x
29 18 = 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
=
0.621
x = 0.621
x = 0.621
