Accepted Solution

A:
8 Divided by What Equals 71? 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 8 by to equal 71? Solving 8 Divided by What Equals 71 Here’s how you would set up this question as an equation: 8 x = 71 \frac{8}{x} = 71 x 8 ​ = 71 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 8: 8 = 71 ∗ x 8 = 71*x 8 = 71 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 71: 8 71 = x \frac{8}{71} = x 71 8 ​ = 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 = 0.113 x = 0.113 x = 0.113 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!
