Solving 90 Divided by What Equals 7 Here’s how you would set up this question as an equation: 90 x = 7 \frac{90}{x} = 7 x 90 ​ = 7 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 90: 90 = 7 ∗ x 90 = 7*x 90 = 7 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 7: 90 7 = x \frac{90}{7} = x 7 90 ​ = 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 = 12.857 x = 12.857 x = 12.857 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!
