78 Divided by What Equals 88?
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 78 by to equal 88?
Solving 78 Divided by What Equals 88
Here’s how you would set up this question as an equation:
78
x
=
88
\frac{78}{x} = 88
x 78 = 88
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 78:
78
=
88
∗
x
78 = 88*x
78 = 88 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 88:
78
88
=
x
\frac{78}{88} = x
88 78 = 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
=
0.886
x = 0.886
x = 0.886
