Accepted Solution

A:
90 Divided by What Equals 36? 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 90 by to equal 36? Solving 90 Divided by What Equals 36 Here’s how you would set up this question as an equation: 90 x = 36 \frac{90}{x} = 36 x 90 ​ = 36 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 90: 90 = 36 ∗ x 90 = 36*x 90 = 36 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 36: 90 36 = x \frac{90}{36} = x 36 90 ​ = 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 = 2.500 x = 2.500 x = 2.500 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!
