What Divided by 85 Equals 9?
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 85, equals 9?
Solving What Divided by 85 Equals 9
Here’s how you would set up this question as an equation:
x
85
=
9
\frac{x}{85} = 9
85 x = 9
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 85, resulting in this equation:
x
=
9
∗
85
x = 9*85
x = 9 ∗ 85
Then we simplify and find our answer:
x
=
765
x = 765
x = 765
So, the answer to the question “What divided by 85 equals 9?” is 765.To prove this, we can take the original problem:
x
85
=
9
\frac{x}{85} = 9
85 x = 9
And insert 765 in the place of x:
765
85
=
9
\frac{765}{85} = 9
85 765 = 9
Because this is true, the answer must be correct.
