Accepted Solution

A:
16 Divided by What Equals 25? 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 16 by to equal 25? Solving 16 Divided by What Equals 25 Here’s how you would set up this question as an equation: 16 x = 25 \frac{16}{x} = 25 x 16 ​ = 25 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 16: 16 = 25 ∗ x 16 = 25*x 16 = 25 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 25: 16 25 = x \frac{16}{25} = x 25 16 ​ = 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 = 0.640 x = 0.640 x = 0.640 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!
