42 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 42 by to equal 50?
Solving 42 Divided by What Equals 50
Here’s how you would set up this question as an equation:
42
x
=
50
\frac{42}{x} = 50
x 42 = 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 42:
42
=
50
∗
x
42 = 50*x
42 = 50 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 50:
42
50
=
x
\frac{42}{50} = x
50 42 = 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
=
0.840
x = 0.840
x = 0.840
