What Divided by 9 Equals 54?
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 54?
Solving What Divided by 9 Equals 54
Here’s how you would set up this question as an equation:
x
9
=
54
\frac{x}{9} = 54
9 x = 54
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
=
54
∗
9
x = 54*9
x = 54 ∗ 9
Then we simplify and find our answer:
x
=
486
x = 486
x = 486
So, the answer to the question “What divided by 9 equals 54?” is 486.To prove this, we can take the original problem:
x
9
=
54
\frac{x}{9} = 54
9 x = 54
And insert 486 in the place of x:
486
9
=
54
\frac{486}{9} = 54
9 486 = 54
Because this is true, the answer must be correct.
