What Divided by 77 Equals 39?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 77, equals 39?Solving What Divided by 77 Equals 39Here’s how you would set up this question as an equation:x77=39\frac{x}{77} = 3977x=39The 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 77, resulting in this equation:x=39∗77x = 39*77x=39∗77Then we simplify and find our answer:x=3003x = 3003x=3003So, the answer to the question “What divided by 77 equals 39?” is 3003.To prove this, we can take the original problem:x77=39\frac{x}{77} = 3977x=39And insert 3003 in the place of x:300377=39\frac{3003}{77} = 39773003=39Because 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 76 equals 84?86 divided by what equals 33?What is 4/13 divided by 57?What is 20/7 divided by 12/15?What is 6 divided by 16/10?
