29 Divided by What Equals 80?
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 29 by to equal 80?
Solving 29 Divided by What Equals 80
Here’s how you would set up this question as an equation:
29
x
=
80
\frac{29}{x} = 80
x 29 = 80
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 29:
29
=
80
∗
x
29 = 80*x
29 = 80 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 80:
29
80
=
x
\frac{29}{80} = x
80 29 = 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
=
0.362
x = 0.362
x = 0.362
