15 Divided by What Equals 9?MethodsSetting 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 15 by to equal 9?Solving 15 Divided by What Equals 9Here’s how you would set up this question as an equation:15x=9\frac{15}{x} = 9x15=9The 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 15:15=9∗x15 = 9*x15=9∗xThen we can isolate x on the right side of the equation by dividing both sides by 9:159=x\frac{15}{9} = x915=xWhen 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=1.667x = 1.667x=1.667Practice Other Division Problems Like This OneIf 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!What divided by 76 equals 89?54 divided by what equals 5?What is 14/8 divided by 51?What is 7/16 divided by 11/6?What is 95 divided by 1/3?
