Solving 16 Divided by What Equals 31 Here’s how you would set up this question as an equation: 16 x = 31 \frac{16}{x} = 31 x 16 ​ = 31 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 16: 16 = 31 ∗ x 16 = 31*x 16 = 31 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 31: 16 31 = x \frac{16}{31} = x 31 16 ​ = 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 = 0.516 x = 0.516 x = 0.516 Practice Other Division Problems Like This One If this problem was a little difficult or you want to practice your skills on another one, give it a go on any one of these too!
