Accepted Solution

A:
10 Divided by What Equals 45? 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 10 by to equal 45? Solving 10 Divided by What Equals 45 Here’s how you would set up this question as an equation: 10 x = 45 \frac{10}{x} = 45 x 10 ​ = 45 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 10: 10 = 45 ∗ x 10 = 45*x 10 = 45 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 45: 10 45 = x \frac{10}{45} = x 45 10 ​ = 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 = 0.222 x = 0.222 x = 0.222 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!
