What Divided by 3 Equals 84?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 84?Solving What Divided by 3 Equals 84Here’s how you would set up this question as an equation:x3=84\frac{x}{3} = 843x=84The 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=84∗3x = 84*3x=84∗3Then we simplify and find our answer:x=252x = 252x=252So, the answer to the question “What divided by 3 equals 84?” is 252.To prove this, we can take the original problem:x3=84\frac{x}{3} = 843x=84And insert 252 in the place of x:2523=84\frac{252}{3} = 843252=84Because 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 30 equals 16?82 divided by what equals 8?What is 13/4 divided by 12?What is 12/19 divided by 15/16?What is 21 divided by 1/14?
