56 Divided by What Equals 30?
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 56 by to equal 30?
Solving 56 Divided by What Equals 30
Here’s how you would set up this question as an equation:
56
x
=
30
\frac{56}{x} = 30
x 56 = 30
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 56:
56
=
30
∗
x
56 = 30*x
56 = 30 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 30:
56
30
=
x
\frac{56}{30} = x
30 56 = 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
=
1.867
x = 1.867
x = 1.867
