A:
8 Divided by What Equals 25?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 8 by to equal 25?Solving 8 Divided by What Equals 25Here’s how you would set up this question as an equation:8x=25\frac{8}{x} = 25x8​=25The 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 8:8=25∗x8 = 25*x8=25∗xThen we can isolate x on the right side of the equation by dividing both sides by 25:825=x\frac{8}{25} = x258​=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=0.320x = 0.320x=0.320Practice 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 97 equals 92?39 divided by what equals 74?What is 2/19 divided by 78?What is 16/3 divided by 10/7?What is 51 divided by 4/1?
