What Divided by 78 Equals 2?
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 78, equals 2?
Solving What Divided by 78 Equals 2
Here’s how you would set up this question as an equation:
x
78
=
2
\frac{x}{78} = 2
78 x = 2
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 78, resulting in this equation:
x
=
2
∗
78
x = 2*78
x = 2 ∗ 78
Then we simplify and find our answer:
x
=
156
x = 156
x = 156
So, the answer to the question “What divided by 78 equals 2?” is 156.To prove this, we can take the original problem:
x
78
=
2
\frac{x}{78} = 2
78 x = 2
And insert 156 in the place of x:
156
78
=
2
\frac{156}{78} = 2
78 156 = 2
Because this is true, the answer must be correct.
