20 Divided by What Equals 53?
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 can we divide 20 by to equal 53?
Solving 20 Divided by What Equals 53
Here’s how you would set up this question as an equation:
20
x
=
53
\frac{20}{x} = 53
x 20 = 53
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, it can be done in two steps. The first step is to multiply both sides by x to isolate 20:
20
=
53
∗
x
20 = 53*x
20 = 53 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 53:
20
53
=
x
\frac{20}{53} = x
53 20 = x
When we simplify the new equation, we can solve for x. In this example, we will round to the nearest three decimal places if that’s needed.
x
=
0.377
x = 0.377
x = 0.377
