86 Divided by What Equals 31?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 31?Solving 86 Divided by What Equals 31Here’s how you would set up this question as an equation:86x=31\frac{86}{x} = 31x86=31The 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=31∗x86 = 31*x86=31∗xThen we can isolate x on the right side of the equation by dividing both sides by 31:8631=x\frac{86}{31} = x3186=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=2.774x = 2.774x=2.774Practice 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 37 equals 14?32 divided by what equals 56?What is 16/3 divided by 9?What is 20/11 divided by 5/17?What is 19 divided by 19/18?
