A:
77 Divided by What Equals 65?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 77 by to equal 65?Solving 77 Divided by What Equals 65Here’s how you would set up this question as an equation:77x=65\frac{77}{x} = 65x77​=65The 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 77:77=65∗x77 = 65*x77=65∗xThen we can isolate x on the right side of the equation by dividing both sides by 65:7765=x\frac{77}{65} = x6577​=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=1.185x = 1.185x=1.185Practice 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 68 equals 12?80 divided by what equals 20?What is 8/3 divided by 18?What is 15/17 divided by 1/13?What is 10 divided by 5/19?
