What Divided by 7 Equals 28?
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 28?
Solving What Divided by 7 Equals 28
Here’s how you would set up this question as an equation:
x
7
=
28
\frac{x}{7} = 28
7 x = 28
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
=
28
∗
7
x = 28*7
x = 28 ∗ 7
Then we simplify and find our answer:
x
=
196
x = 196
x = 196
So, the answer to the question “What divided by 7 equals 28?” is 196.To prove this, we can take the original problem:
x
7
=
28
\frac{x}{7} = 28
7 x = 28
And insert 196 in the place of x:
196
7
=
28
\frac{196}{7} = 28
7 196 = 28
Because this is true, the answer must be correct.
