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