A:
71 Divided by What Equals 28? 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 71 by to equal 28? Solving 71 Divided by What Equals 28 Here’s how you would set up this question as an equation: 71 x = 28 \frac{71}{x} = 28 x 71 ​ = 28 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 71: 71 = 28 ∗ x 71 = 28*x 71 = 28 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 28: 71 28 = x \frac{71}{28} = x 28 71 ​ = 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 = 2.536 x = 2.536 x = 2.536 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!
