Accepted Solution

A:
45 Divided by What Equals 12? 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 45 by to equal 12? Solving 45 Divided by What Equals 12 Here’s how you would set up this question as an equation: 45 x = 12 \frac{45}{x} = 12 x 45 ​ = 12 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 45: 45 = 12 ∗ x 45 = 12*x 45 = 12 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 12: 45 12 = x \frac{45}{12} = x 12 45 ​ = 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 = 3.750 x = 3.750 x = 3.750 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!
