What Divided by 51 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 51, equals 2?
Solving What Divided by 51 Equals 2
Here’s how you would set up this question as an equation:
x
51
=
2
\frac{x}{51} = 2
51 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 51, resulting in this equation:
x
=
2
∗
51
x = 2*51
x = 2 ∗ 51
Then we simplify and find our answer:
x
=
102
x = 102
x = 102
So, the answer to the question “What divided by 51 equals 2?” is 102.To prove this, we can take the original problem:
x
51
=
2
\frac{x}{51} = 2
51 x = 2
And insert 102 in the place of x:
102
51
=
2
\frac{102}{51} = 2
51 102 = 2
Because this is true, the answer must be correct.
