47 Divided by What Equals 91?
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 47 by to equal 91?
Solving 47 Divided by What Equals 91
Here’s how you would set up this question as an equation:
47
x
=
91
\frac{47}{x} = 91
x 47 = 91
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 47:
47
=
91
∗
x
47 = 91*x
47 = 91 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 91:
47
91
=
x
\frac{47}{91} = x
91 47 = 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
=
0.516
x = 0.516
x = 0.516
