What Divided by 9 Equals 13?
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 9, equals 13?
Solving What Divided by 9 Equals 13
Here’s how you would set up this question as an equation:
x
9
=
13
\frac{x}{9} = 13
9 x = 13
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 9, resulting in this equation:
x
=
13
∗
9
x = 13*9
x = 13 ∗ 9
Then we simplify and find our answer:
x
=
117
x = 117
x = 117
So, the answer to the question “What divided by 9 equals 13?” is 117.To prove this, we can take the original problem:
x
9
=
13
\frac{x}{9} = 13
9 x = 13
And insert 117 in the place of x:
117
9
=
13
\frac{117}{9} = 13
9 117 = 13
Because this is true, the answer must be correct.
