A:
87 Divided by What Equals 74? 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 87 by to equal 74? Solving 87 Divided by What Equals 74 Here’s how you would set up this question as an equation: 87 x = 74 \frac{87}{x} = 74 x 87 ​ = 74 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 87: 87 = 74 ∗ x 87 = 74*x 87 = 74 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 74: 87 74 = x \frac{87}{74} = x 74 87 ​ = 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 = 1.176 x = 1.176 x = 1.176 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!
