A:
42 Divided by What Equals 85? 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 42 by to equal 85? Solving 42 Divided by What Equals 85 Here’s how you would set up this question as an equation: 42 x = 85 \frac{42}{x} = 85 x 42 ​ = 85 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 42: 42 = 85 ∗ x 42 = 85*x 42 = 85 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 85: 42 85 = x \frac{42}{85} = x 85 42 ​ = 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 = 0.494 x = 0.494 x = 0.494 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!
