What Divided by 13 Equals 4?
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 13, equals 4?
Solving What Divided by 13 Equals 4
Here’s how you would set up this question as an equation:
x
13
=
4
\frac{x}{13} = 4
13 x = 4
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 13, resulting in this equation:
x
=
4
∗
13
x = 4*13
x = 4 ∗ 13
Then we simplify and find our answer:
x
=
52
x = 52
x = 52
So, the answer to the question “What divided by 13 equals 4?” is 52.To prove this, we can take the original problem:
x
13
=
4
\frac{x}{13} = 4
13 x = 4
And insert 52 in the place of x:
52
13
=
4
\frac{52}{13} = 4
13 52 = 4
Because this is true, the answer must be correct.
