What Divided by 8 Equals 30?
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 30?
Solving What Divided by 8 Equals 30
Here’s how you would set up this question as an equation:
x
8
=
30
\frac{x}{8} = 30
8 x = 30
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
=
30
∗
8
x = 30*8
x = 30 ∗ 8
Then we simplify and find our answer:
x
=
240
x = 240
x = 240
So, the answer to the question “What divided by 8 equals 30?” is 240.To prove this, we can take the original problem:
x
8
=
30
\frac{x}{8} = 30
8 x = 30
And insert 240 in the place of x:
240
8
=
30
\frac{240}{8} = 30
8 240 = 30
Because this is true, the answer must be correct.
