1 Divided by What Equals 77?
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 1 by to equal 77?
Solving 1 Divided by What Equals 77
Here’s how you would set up this question as an equation:
1
x
=
77
\frac{1}{x} = 77
x 1 = 77
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 1:
1
=
77
∗
x
1 = 77*x
1 = 77 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 77:
1
77
=
x
\frac{1}{77} = x
77 1 = 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
=
0.013
x = 0.013
x = 0.013
