What Divided by 8 Equals 89?
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 8, equals 89?
Solving What Divided by 8 Equals 89
Here’s how you would set up this question as an equation:
x
8
=
89
\frac{x}{8} = 89
8 x = 89
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 8, resulting in this equation:
x
=
89
∗
8
x = 89*8
x = 89 ∗ 8
Then we simplify and find our answer:
x
=
712
x = 712
x = 712
So, the answer to the question “What divided by 8 equals 89?” is 712.To prove this, we can take the original problem:
x
8
=
89
\frac{x}{8} = 89
8 x = 89
And insert 712 in the place of x:
712
8
=
89
\frac{712}{8} = 89
8 712 = 89
Because this is true, the answer must be correct.
