75 Divided by What Equals 7?
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 75 by to equal 7?
Solving 75 Divided by What Equals 7
Here’s how you would set up this question as an equation:
75
x
=
7
\frac{75}{x} = 7
x 75 = 7
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 75:
75
=
7
∗
x
75 = 7*x
75 = 7 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 7:
75
7
=
x
\frac{75}{7} = x
7 75 = 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
=
10.714
x = 10.714
x = 10.714
