43 Divided by What 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 can we divide 43 by to equal 28?
Solving 43 Divided by What Equals 28
Here’s how you would set up this question as an equation:
43
x
=
28
\frac{43}{x} = 28
x 43 = 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, it can be done in two steps. The first step is to multiply both sides by x to isolate 43:
43
=
28
∗
x
43 = 28*x
43 = 28 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 28:
43
28
=
x
\frac{43}{28} = x
28 43 = 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
=
1.536
x = 1.536
x = 1.536
