What Divided by 3 Equals 31?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 3, equals 31?Solving What Divided by 3 Equals 31Here’s how you would set up this question as an equation:x3=31\frac{x}{3} = 313x=31The 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 3, resulting in this equation:x=31∗3x = 31*3x=31∗3Then we simplify and find our answer:x=93x = 93x=93So, the answer to the question “What divided by 3 equals 31?” is 93.To prove this, we can take the original problem:x3=31\frac{x}{3} = 313x=31And insert 93 in the place of x:933=31\frac{93}{3} = 31393=31Because 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 2 equals 63?36 divided by what equals 99?What is 10/13 divided by 84?What is 11/16 divided by 17/7?What is 11 divided by 4/20?
