What Divided by 51 Equals 30?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 30?Solving What Divided by 51 Equals 30Here’s how you would set up this question as an equation:x51=30\frac{x}{51} = 3051x=30The 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=30∗51x = 30*51x=30∗51Then we simplify and find our answer:x=1530x = 1530x=1530So, the answer to the question “What divided by 51 equals 30?” is 1530.To prove this, we can take the original problem:x51=30\frac{x}{51} = 3051x=30And insert 1530 in the place of x:153051=30\frac{1530}{51} = 30511530=30Because 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 41 equals 27?31 divided by what equals 71?What is 6/17 divided by 19?What is 3/4 divided by 12/16?What is 48 divided by 20/10?
