28 Divided by What Equals 56?
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 28 by to equal 56?
Solving 28 Divided by What Equals 56
Here’s how you would set up this question as an equation:
28
x
=
56
\frac{28}{x} = 56
x 28 = 56
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 28:
28
=
56
∗
x
28 = 56*x
28 = 56 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 56:
28
56
=
x
\frac{28}{56} = x
56 28 = 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
=
0.500
x = 0.500
x = 0.500
