14 Divided by What Equals 40?
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 14 by to equal 40?
Solving 14 Divided by What Equals 40
Here’s how you would set up this question as an equation:
14
x
=
40
\frac{14}{x} = 40
x 14 = 40
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 14:
14
=
40
∗
x
14 = 40*x
14 = 40 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 40:
14
40
=
x
\frac{14}{40} = x
40 14 = 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
=
0.350
x = 0.350
x = 0.350
