A:
28 Divided by What Equals 51? 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 28 by to equal 51? Solving 28 Divided by What Equals 51 Here’s how you would set up this question as an equation: 28 x = 51 \frac{28}{x} = 51 x 28 ​ = 51 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 28: 28 = 51 ∗ x 28 = 51*x 28 = 51 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 51: 28 51 = x \frac{28}{51} = x 51 28 ​ = 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 = 0.549 x = 0.549 x = 0.549 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!
