What Divided by 5 Equals 91?
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 5, equals 91?
Solving What Divided by 5 Equals 91
Here’s how you would set up this question as an equation:
x
5
=
91
\frac{x}{5} = 91
5 x = 91
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 5, resulting in this equation:
x
=
91
∗
5
x = 91*5
x = 91 ∗ 5
Then we simplify and find our answer:
x
=
455
x = 455
x = 455
So, the answer to the question “What divided by 5 equals 91?” is 455.To prove this, we can take the original problem:
x
5
=
91
\frac{x}{5} = 91
5 x = 91
And insert 455 in the place of x:
455
5
=
91
\frac{455}{5} = 91
5 455 = 91
Because this is true, the answer must be correct.
