15 Divided by What Equals 1?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 1?Solving 15 Divided by What Equals 1Here’s how you would set up this question as an equation:15x=1\frac{15}{x} = 1x15=1The 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=1∗x15 = 1*x15=1∗xThen we can isolate x on the right side of the equation by dividing both sides by 1:151=x\frac{15}{1} = x115=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=15.000x = 15.000x=15.000Practice 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 18 equals 93?96 divided by what equals 97?What is 7/10 divided by 20?What is 3/20 divided by 12/14?What is 80 divided by 8/4?
