A:
15 Divided by What Equals 6?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 6?Solving 15 Divided by What Equals 6Here’s how you would set up this question as an equation:15x=6\frac{15}{x} = 6x15​=6The 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=6∗x15 = 6*x15=6∗xThen we can isolate x on the right side of the equation by dividing both sides by 6:156=x\frac{15}{6} = x615​=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=2.500x = 2.500x=2.500Practice 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 38 equals 85?60 divided by what equals 78?What is 14/19 divided by 83?What is 3/4 divided by 2/20?What is 33 divided by 1/7?
