What Divided by 77 Equals 1?
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 77, equals 1?
Solving What Divided by 77 Equals 1
Here’s how you would set up this question as an equation:
x
77
=
1
\frac{x}{77} = 1
77 x = 1
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 77, resulting in this equation:
x
=
1
∗
77
x = 1*77
x = 1 ∗ 77
Then we simplify and find our answer:
x
=
77
x = 77
x = 77
So, the answer to the question “What divided by 77 equals 1?” is 77.To prove this, we can take the original problem:
x
77
=
1
\frac{x}{77} = 1
77 x = 1
And insert 77 in the place of x:
77
77
=
1
\frac{77}{77} = 1
77 77 = 1
Because this is true, the answer must be correct.
