A:
85 Divided by What Equals 75? 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 85 by to equal 75? Solving 85 Divided by What Equals 75 Here’s how you would set up this question as an equation: 85 x = 75 \frac{85}{x} = 75 x 85 ​ = 75 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 85: 85 = 75 ∗ x 85 = 75*x 85 = 75 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 75: 85 75 = x \frac{85}{75} = x 75 85 ​ = 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 = 1.133 x = 1.133 x = 1.133 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!
