What Divided by 84 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 84, equals 3?
Solving What Divided by 84 Equals 3
Here’s how you would set up this question as an equation:
x
84
=
3
\frac{x}{84} = 3
84 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 84, resulting in this equation:
x
=
3
∗
84
x = 3*84
x = 3 ∗ 84
Then we simplify and find our answer:
x
=
252
x = 252
x = 252
So, the answer to the question “What divided by 84 equals 3?” is 252.To prove this, we can take the original problem:
x
84
=
3
\frac{x}{84} = 3
84 x = 3
And insert 252 in the place of x:
252
84
=
3
\frac{252}{84} = 3
84 252 = 3
Because this is true, the answer must be correct.
