Solving 66 Divided by What Equals 7 Here’s how you would set up this question as an equation: 66 x = 7 \frac{66}{x} = 7 x 66 ​ = 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 66: 66 = 7 ∗ x 66 = 7*x 66 = 7 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 7: 66 7 = x \frac{66}{7} = x 7 66 ​ = 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 = 9.429 x = 9.429 x = 9.429 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!
