What Divided by 4 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 4, equals 30?
Solving What Divided by 4 Equals 30
Here’s how you would set up this question as an equation:
x
4
=
30
\frac{x}{4} = 30
4 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 4, resulting in this equation:
x
=
30
∗
4
x = 30*4
x = 30 ∗ 4
Then we simplify and find our answer:
x
=
120
x = 120
x = 120
So, the answer to the question “What divided by 4 equals 30?” is 120.To prove this, we can take the original problem:
x
4
=
30
\frac{x}{4} = 30
4 x = 30
And insert 120 in the place of x:
120
4
=
30
\frac{120}{4} = 30
4 120 = 30
Because this is true, the answer must be correct.
