A:
82 Divided by What Equals 72? 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 82 by to equal 72? Solving 82 Divided by What Equals 72 Here’s how you would set up this question as an equation: 82 x = 72 \frac{82}{x} = 72 x 82 ​ = 72 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 82: 82 = 72 ∗ x 82 = 72*x 82 = 72 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 72: 82 72 = x \frac{82}{72} = x 72 82 ​ = 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 = 1.139 x = 1.139 x = 1.139 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!
