Accepted Solution

5 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 5 by to equal 8? Solving 5 Divided by What Equals 8 Here’s how you would set up this question as an equation: 5 x = 8 \frac{5}{x} = 8 x 5 ​ = 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 5: 5 = 8 ∗ x 5 = 8*x 5 = 8 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 8: 5 8 = x \frac{5}{8} = x 8 5 ​ = 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 = 0.625 x = 0.625 x = 0.625 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!
