What Divided by 30 Equals 5?
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 30, equals 5?
Solving What Divided by 30 Equals 5
Here’s how you would set up this question as an equation:
x
30
=
5
\frac{x}{30} = 5
30 x = 5
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 30, resulting in this equation:
x
=
5
∗
30
x = 5*30
x = 5 ∗ 30
Then we simplify and find our answer:
x
=
150
x = 150
x = 150
So, the answer to the question “What divided by 30 equals 5?” is 150.To prove this, we can take the original problem:
x
30
=
5
\frac{x}{30} = 5
30 x = 5
And insert 150 in the place of x:
150
30
=
5
\frac{150}{30} = 5
30 150 = 5
Because this is true, the answer must be correct.
