What Divided by 3 Equals 99?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 99?Solving What Divided by 3 Equals 99Here’s how you would set up this question as an equation:x3=99\frac{x}{3} = 993x=99The 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=99∗3x = 99*3x=99∗3Then we simplify and find our answer:x=297x = 297x=297So, the answer to the question “What divided by 3 equals 99?” is 297.To prove this, we can take the original problem:x3=99\frac{x}{3} = 993x=99And insert 297 in the place of x:2973=99\frac{297}{3} = 993297=99Because 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 79 equals 27?52 divided by what equals 21?What is 1/14 divided by 10?What is 13/12 divided by 15/19?What is 98 divided by 16/17?
