What Divided by 18 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, when divided by 18, equals 1?
Solving What Divided by 18 Equals 1
Here’s how you would set up this question as an equation:
x
18
=
1
\frac{x}{18} = 1
18 x = 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, we can do that by multiplying both sides of the equation by 18, resulting in this equation:
x
=
1
∗
18
x = 1*18
x = 1 ∗ 18
Then we simplify and find our answer:
x
=
18
x = 18
x = 18
So, the answer to the question “What divided by 18 equals 1?” is 18.To prove this, we can take the original problem:
x
18
=
1
\frac{x}{18} = 1
18 x = 1
And insert 18 in the place of x:
18
18
=
1
\frac{18}{18} = 1
18 18 = 1
Because this is true, the answer must be correct.
