Accepted Solution

3 Divided by What Equals 66? Methods Setting 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 can we divide 3 by to equal 66? Solving 3 Divided by What Equals 66 Here’s how you would set up this question as an equation: 3 x = 66 \frac{3}{x} = 66 x 3 ​ = 66 The 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, it can be done in two steps. The first step is to multiply both sides by x to isolate 3: 3 = 66 ∗ x 3 = 66*x 3 = 66 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 66: 3 66 = x \frac{3}{66} = x 66 3 ​ = x When we simplify the new equation, we can solve for x. In this example, we will round to the nearest three decimal places if that’s needed. x = 0.045 x = 0.045 x = 0.045 Practice Other Division Problems Like This One If 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!
