Accepted Solution

7 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 7 by to equal 8? Solving 7 Divided by What Equals 8 Here’s how you would set up this question as an equation: 7 x = 8 \frac{7}{x} = 8 x 7 ​ = 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 7: 7 = 8 ∗ x 7 = 8*x 7 = 8 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 8: 7 8 = x \frac{7}{8} = x 8 7 ​ = 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 = 0.875 x = 0.875 x = 0.875 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!
