16 Divided by What Equals 3?
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 16 by to equal 3?
Solving 16 Divided by What Equals 3
Here’s how you would set up this question as an equation:
16
x
=
3
\frac{16}{x} = 3
x 16 = 3
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 16:
16
=
3
∗
x
16 = 3*x
16 = 3 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 3:
16
3
=
x
\frac{16}{3} = x
3 16 = 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
=
5.333
x = 5.333
x = 5.333
