Accepted Solution

A:
23 Divided by What Equals 40? 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 23 by to equal 40? Solving 23 Divided by What Equals 40 Here’s how you would set up this question as an equation: 23 x = 40 \frac{23}{x} = 40 x 23 ​ = 40 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 23: 23 = 40 ∗ x 23 = 40*x 23 = 40 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 40: 23 40 = x \frac{23}{40} = x 40 23 ​ = 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 = 0.575 x = 0.575 x = 0.575 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!
