55 Divided by What Equals 79?
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 55 by to equal 79?
Solving 55 Divided by What Equals 79
Here’s how you would set up this question as an equation:
55
x
=
79
\frac{55}{x} = 79
x 55 = 79
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 55:
55
=
79
∗
x
55 = 79*x
55 = 79 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 79:
55
79
=
x
\frac{55}{79} = x
79 55 = 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
=
0.696
x = 0.696
x = 0.696
