86 Divided by What Equals 27?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 86 by to equal 27?Solving 86 Divided by What Equals 27Here’s how you would set up this question as an equation:86x=27\frac{86}{x} = 27x86​=27The 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 86:86=27∗x86 = 27*x86=27∗xThen we can isolate x on the right side of the equation by dividing both sides by 27:8627=x\frac{86}{27} = x2786​=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=3.185x = 3.185x=3.185Practice 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 64 equals 20?10 divided by what equals 99?What is 12/2 divided by 52?What is 5/1 divided by 18/3?What is 77 divided by 6/7?
