Accepted Solution

1 Divided by What Equals 20? 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 1 by to equal 20? Solving 1 Divided by What Equals 20 Here’s how you would set up this question as an equation: 1 x = 20 \frac{1}{x} = 20 x 1 ​ = 20 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 1: 1 = 20 ∗ x 1 = 20*x 1 = 20 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 20: 1 20 = x \frac{1}{20} = x 20 1 ​ = 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 = 0.050 x = 0.050 x = 0.050 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!
