What Divided by 7 Equals 80?
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 7, equals 80?
Solving What Divided by 7 Equals 80
Here’s how you would set up this question as an equation:
x
7
=
80
\frac{x}{7} = 80
7 x = 80
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 7, resulting in this equation:
x
=
80
∗
7
x = 80*7
x = 80 ∗ 7
Then we simplify and find our answer:
x
=
560
x = 560
x = 560
So, the answer to the question “What divided by 7 equals 80?” is 560.To prove this, we can take the original problem:
x
7
=
80
\frac{x}{7} = 80
7 x = 80
And insert 560 in the place of x:
560
7
=
80
\frac{560}{7} = 80
7 560 = 80
Because this is true, the answer must be correct.
