What Divided by 79 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 79, equals 9?
Solving What Divided by 79 Equals 9
Here’s how you would set up this question as an equation:
x
79
=
9
\frac{x}{79} = 9
79 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 79, resulting in this equation:
x
=
9
∗
79
x = 9*79
x = 9 ∗ 79
Then we simplify and find our answer:
x
=
711
x = 711
x = 711
So, the answer to the question “What divided by 79 equals 9?” is 711.To prove this, we can take the original problem:
x
79
=
9
\frac{x}{79} = 9
79 x = 9
And insert 711 in the place of x:
711
79
=
9
\frac{711}{79} = 9
79 711 = 9
Because this is true, the answer must be correct.
