86 Divided by What Equals 19?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 19?Solving 86 Divided by What Equals 19Here’s how you would set up this question as an equation:86x=19\frac{86}{x} = 19x86=19The 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=19∗x86 = 19*x86=19∗xThen we can isolate x on the right side of the equation by dividing both sides by 19:8619=x\frac{86}{19} = x1986=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=4.526x = 4.526x=4.526Practice 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 40 equals 31?1 divided by what equals 10?What is 10/4 divided by 7?What is 14/3 divided by 16/5?What is 27 divided by 12/8?
