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