86 Divided by What Equals 47?
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 86 by to equal 47?
Solving 86 Divided by What Equals 47
Here’s how you would set up this question as an equation:
86
x
=
47
\frac{86}{x} = 47
x 86 = 47
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 86:
86
=
47
∗
x
86 = 47*x
86 = 47 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 47:
86
47
=
x
\frac{86}{47} = x
47 86 = 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
=
1.830
x = 1.830
x = 1.830
