What Divided by 51 Equals 69?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 51, equals 69?Solving What Divided by 51 Equals 69Here’s how you would set up this question as an equation:x51=69\frac{x}{51} = 6951x=69The 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 51, resulting in this equation:x=69∗51x = 69*51x=69∗51Then we simplify and find our answer:x=3519x = 3519x=3519So, the answer to the question “What divided by 51 equals 69?” is 3519.To prove this, we can take the original problem:x51=69\frac{x}{51} = 6951x=69And insert 3519 in the place of x:351951=69\frac{3519}{51} = 69513519=69Because 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 5 equals 16?9 divided by what equals 57?What is 14/10 divided by 61?What is 16/11 divided by 6/7?What is 20 divided by 1/9?
