90 Divided by What Equals 50?
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 90 by to equal 50?
Solving 90 Divided by What Equals 50
Here’s how you would set up this question as an equation:
90
x
=
50
\frac{90}{x} = 50
x 90 = 50
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 90:
90
=
50
∗
x
90 = 50*x
90 = 50 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 50:
90
50
=
x
\frac{90}{50} = x
50 90 = 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
=
1.800
x = 1.800
x = 1.800
