Accepted Solution

A:
71 Divided by What Equals 8? 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 71 by to equal 8? Solving 71 Divided by What Equals 8 Here’s how you would set up this question as an equation: 71 x = 8 \frac{71}{x} = 8 x 71 ​ = 8 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 71: 71 = 8 ∗ x 71 = 8*x 71 = 8 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 8: 71 8 = x \frac{71}{8} = x 8 71 ​ = 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 = 8.875 x = 8.875 x = 8.875 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!
