77 Divided by What Equals 23?
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 77 by to equal 23?
Solving 77 Divided by What Equals 23
Here’s how you would set up this question as an equation:
77
x
=
23
\frac{77}{x} = 23
x 77 = 23
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 77:
77
=
23
∗
x
77 = 23*x
77 = 23 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 23:
77
23
=
x
\frac{77}{23} = x
23 77 = 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
=
3.348
x = 3.348
x = 3.348
