48 Divided by What Equals 55?
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 55?
Solving 48 Divided by What Equals 55
Here’s how you would set up this question as an equation:
48
x
=
55
\frac{48}{x} = 55
x 48 = 55
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
=
55
∗
x
48 = 55*x
48 = 55 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 55:
48
55
=
x
\frac{48}{55} = x
55 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
=
0.873
x = 0.873
x = 0.873
