40 Divided by What Equals 1?
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 40 by to equal 1?
Solving 40 Divided by What Equals 1
Here’s how you would set up this question as an equation:
40
x
=
1
\frac{40}{x} = 1
x 40 = 1
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 40:
40
=
1
∗
x
40 = 1*x
40 = 1 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 1:
40
1
=
x
\frac{40}{1} = x
1 40 = 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
=
40.000
x = 40.000
x = 40.000
