A:
77 Divided by What Equals 10?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 10?Solving 77 Divided by What Equals 10Here’s how you would set up this question as an equation:77x=10\frac{77}{x} = 10x77​=10The 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=10∗x77 = 10*x77=10∗xThen we can isolate x on the right side of the equation by dividing both sides by 10:7710=x\frac{77}{10} = x1077​=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=7.700x = 7.700x=7.700Practice 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 36 equals 62?29 divided by what equals 11?What is 7/15 divided by 96?What is 8/4 divided by 6/14?What is 84 divided by 3/17?
