What Divided by 51 Equals 72?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 72?Solving What Divided by 51 Equals 72Here’s how you would set up this question as an equation:x51=72\frac{x}{51} = 7251x=72The 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=72∗51x = 72*51x=72∗51Then we simplify and find our answer:x=3672x = 3672x=3672So, the answer to the question “What divided by 51 equals 72?” is 3672.To prove this, we can take the original problem:x51=72\frac{x}{51} = 7251x=72And insert 3672 in the place of x:367251=72\frac{3672}{51} = 72513672=72Because 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 42 equals 87?97 divided by what equals 29?What is 14/11 divided by 10?What is 9/4 divided by 3/8?What is 36 divided by 19/5?
