What Divided by 2 Equals 77?
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 2, equals 77?
Solving What Divided by 2 Equals 77
Here’s how you would set up this question as an equation:
x
2
=
77
\frac{x}{2} = 77
2 x = 77
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 2, resulting in this equation:
x
=
77
∗
2
x = 77*2
x = 77 ∗ 2
Then we simplify and find our answer:
x
=
154
x = 154
x = 154
So, the answer to the question “What divided by 2 equals 77?” is 154.To prove this, we can take the original problem:
x
2
=
77
\frac{x}{2} = 77
2 x = 77
And insert 154 in the place of x:
154
2
=
77
\frac{154}{2} = 77
2 154 = 77
Because this is true, the answer must be correct.
