Accepted Solution

A:
20 Divided by What Equals 10? 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 20 by to equal 10? Solving 20 Divided by What Equals 10 Here’s how you would set up this question as an equation: 20 x = 10 \frac{20}{x} = 10 x 20 ​ = 10 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 20: 20 = 10 ∗ x 20 = 10*x 20 = 10 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 10: 20 10 = x \frac{20}{10} = x 10 20 ​ = 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 = 2.000 x = 2.000 x = 2.000 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!
