What Divided by 80 Equals 3?
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 80, equals 3?
Solving What Divided by 80 Equals 3
Here’s how you would set up this question as an equation:
x
80
=
3
\frac{x}{80} = 3
80 x = 3
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 80, resulting in this equation:
x
=
3
∗
80
x = 3*80
x = 3 ∗ 80
Then we simplify and find our answer:
x
=
240
x = 240
x = 240
So, the answer to the question “What divided by 80 equals 3?” is 240.To prove this, we can take the original problem:
x
80
=
3
\frac{x}{80} = 3
80 x = 3
And insert 240 in the place of x:
240
80
=
3
\frac{240}{80} = 3
80 240 = 3
Because this is true, the answer must be correct.
