Accepted Solution

A:

79 Divided by What Equals 51?
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 79 by to equal 51?
Solving 79 Divided by What Equals 51
Here’s how you would set up this question as an equation:
79
x
=
51
\frac{79}{x} = 51
x 79 = 51
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 79:
79
=
51
∗
x
79 = 51*x
79 = 51 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 51:
79
51
=
x
\frac{79}{51} = x
51 79 = 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
=
1.549
x = 1.549
x = 1.549
