31 Divided by What Equals 98?
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 31 by to equal 98?
Solving 31 Divided by What Equals 98
Here’s how you would set up this question as an equation:
31
x
=
98
\frac{31}{x} = 98
x 31 = 98
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 31:
31
=
98
∗
x
31 = 98*x
31 = 98 ∗ x
Then we can isolate x on the right side of the equation by dividing both sides by 98:
31
98
=
x
\frac{31}{98} = x
98 31 = 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
=
0.316
x = 0.316
x = 0.316
