80 Divided by What Equals 69?
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 80 by to equal 69?
Solving 80 Divided by What Equals 69
Here’s how you would set up this question as an equation:
80
x
=
69
\frac{80}{x} = 69
x 80 = 69
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 80:
80
=
69
∗
x
80 = 69*x
80 = 69 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 69:
80
69
=
x
\frac{80}{69} = x
69 80 = 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
=
1.159
x = 1.159
x = 1.159
