What Divided by 20 Equals 5?
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 20, equals 5?
Solving What Divided by 20 Equals 5
Here’s how you would set up this question as an equation:
x
20
=
5
\frac{x}{20} = 5
20 x = 5
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 20, resulting in this equation:
x
=
5
∗
20
x = 5*20
x = 5 ∗ 20
Then we simplify and find our answer:
x
=
100
x = 100
x = 100
So, the answer to the question “What divided by 20 equals 5?” is 100.To prove this, we can take the original problem:
x
20
=
5
\frac{x}{20} = 5
20 x = 5
And insert 100 in the place of x:
100
20
=
5
\frac{100}{20} = 5
20 100 = 5
Because this is true, the answer must be correct.
