48 Divided by What Equals 45?
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 48 by to equal 45?
Solving 48 Divided by What Equals 45
Here’s how you would set up this question as an equation:
48
x
=
45
\frac{48}{x} = 45
x 48 = 45
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 48:
48
=
45
∗
x
48 = 45*x
48 = 45 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 45:
48
45
=
x
\frac{48}{45} = x
45 48 = 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
=
1.067
x = 1.067
x = 1.067
