What Divided by 77 Equals 7?
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 7?
Solving What Divided by 77 Equals 7
Here’s how you would set up this question as an equation:
x
77
=
7
\frac{x}{77} = 7
77 x = 7
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
=
7
∗
77
x = 7*77
x = 7 ∗ 77
Then we simplify and find our answer:
x
=
539
x = 539
x = 539
So, the answer to the question “What divided by 77 equals 7?” is 539.To prove this, we can take the original problem:
x
77
=
7
\frac{x}{77} = 7
77 x = 7
And insert 539 in the place of x:
539
77
=
7
\frac{539}{77} = 7
77 539 = 7
Because this is true, the answer must be correct.
