30 Divided by What Equals 61?
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 30 by to equal 61?
Solving 30 Divided by What Equals 61
Here’s how you would set up this question as an equation:
30
x
=
61
\frac{30}{x} = 61
x 30 = 61
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 30:
30
=
61
∗
x
30 = 61*x
30 = 61 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 61:
30
61
=
x
\frac{30}{61} = x
61 30 = 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
=
0.492
x = 0.492
x = 0.492
