A:
89 Divided by What Equals 47? 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 89 by to equal 47? Solving 89 Divided by What Equals 47 Here’s how you would set up this question as an equation: 89 x = 47 \frac{89}{x} = 47 x 89 ​ = 47 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 89: 89 = 47 ∗ x 89 = 47*x 89 = 47 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 47: 89 47 = x \frac{89}{47} = x 47 89 ​ = 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 = 1.894 x = 1.894 x = 1.894 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!
