Accepted Solution

A:
21 Divided by What Equals 44? 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 21 by to equal 44? Solving 21 Divided by What Equals 44 Here’s how you would set up this question as an equation: 21 x = 44 \frac{21}{x} = 44 x 21 ​ = 44 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 21: 21 = 44 ∗ x 21 = 44*x 21 = 44 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 44: 21 44 = x \frac{21}{44} = x 44 21 ​ = 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 = 0.477 x = 0.477 x = 0.477 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!
