51 Divided by What Equals 25?
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 51 by to equal 25?
Solving 51 Divided by What Equals 25
Here’s how you would set up this question as an equation:
51
x
=
25
\frac{51}{x} = 25
x 51 = 25
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 51:
51
=
25
∗
x
51 = 25*x
51 = 25 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 25:
51
25
=
x
\frac{51}{25} = x
25 51 = 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
=
2.040
x = 2.040
x = 2.040
