What Divided by 3 Equals 42?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 42?Solving What Divided by 3 Equals 42Here’s how you would set up this question as an equation:x3=42\frac{x}{3} = 423x=42The 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=42∗3x = 42*3x=42∗3Then we simplify and find our answer:x=126x = 126x=126So, the answer to the question “What divided by 3 equals 42?” is 126.To prove this, we can take the original problem:x3=42\frac{x}{3} = 423x=42And insert 126 in the place of x:1263=42\frac{126}{3} = 423126=42Because 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 66 equals 6?67 divided by what equals 22?What is 10/17 divided by 24?What is 12/1 divided by 16/8?What is 44 divided by 11/15?
