What Divided by 22 Equals 81?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, when divided by 22, equals 81?Solving What Divided by 22 Equals 81Here’s how you would set up this question as an equation:x22=81\frac{x}{22} = 8122x=81The 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, we can do that by multiplying both sides of the equation by 22, resulting in this equation:x=81∗22x = 81*22x=81∗22Then we simplify and find our answer:x=1782x = 1782x=1782So, the answer to the question “What divided by 22 equals 81?” is 1782.To prove this, we can take the original problem:x22=81\frac{x}{22} = 8122x=81And insert 1782 in the place of x:178222=81\frac{1782}{22} = 81221782=81Because this is true, the answer must be correct.Practice 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 9 equals 86?16 divided by what equals 39?What is 19/4 divided by 79?What is 15/14 divided by 18/7?What is 47 divided by 13/17?
