91 Divided by What Equals 2?

Accepted Solution

A:
91 Divided by What Equals 2? 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 91 by to equal 2? Solving 91 Divided by What Equals 2 Here’s how you would set up this question as an equation: 91 x = 2 \frac{91}{x} = 2 x 91 ​ = 2 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 91: 91 = 2 ∗ x 91 = 2*x 91 = 2 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 2: 91 2 = x \frac{91}{2} = x 2 91 ​ = 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 = 45.500 x = 45.500 x = 45.500 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!
