A:
72 Divided by What Equals 57? 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 72 by to equal 57? Solving 72 Divided by What Equals 57 Here’s how you would set up this question as an equation: 72 x = 57 \frac{72}{x} = 57 x 72 ​ = 57 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 72: 72 = 57 ∗ x 72 = 57*x 72 = 57 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 57: 72 57 = x \frac{72}{57} = x 57 72 ​ = 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 = 1.263 x = 1.263 x = 1.263 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!
