What Divided by 77 Equals 57?
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 57?
Solving What Divided by 77 Equals 57
Here’s how you would set up this question as an equation:
x
77
=
57
\frac{x}{77} = 57
77 x = 57
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
=
57
∗
77
x = 57*77
x = 57 ∗ 77
Then we simplify and find our answer:
x
=
4389
x = 4389
x = 4389
So, the answer to the question “What divided by 77 equals 57?” is 4389.To prove this, we can take the original problem:
x
77
=
57
\frac{x}{77} = 57
77 x = 57
And insert 4389 in the place of x:
4389
77
=
57
\frac{4389}{77} = 57
77 4389 = 57
Because this is true, the answer must be correct.
