49 Divided by What Equals 39?
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 49 by to equal 39?
Solving 49 Divided by What Equals 39
Here’s how you would set up this question as an equation:
49
x
=
39
\frac{49}{x} = 39
x 49 = 39
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 49:
49
=
39
∗
x
49 = 39*x
49 = 39 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 39:
49
39
=
x
\frac{49}{39} = x
39 49 = 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
=
1.256
x = 1.256
x = 1.256
