31 Divided by What Equals 23? 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 23? Solving 31 Divided by What Equals 23 Here’s how you would set up this question as an equation: 31 x = 23 \frac{31}{x} = 23 x 31 ​ = 23 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 = 23 ∗ x 31 = 23*x 31 = 23 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 23: 31 23 = x \frac{31}{23} = x 23 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 = 1.348 x = 1.348 x = 1.348 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!
