Accepted Solution

A:
43 Divided by What Equals 91? 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 43 by to equal 91? Solving 43 Divided by What Equals 91 Here’s how you would set up this question as an equation: 43 x = 91 \frac{43}{x} = 91 x 43 ​ = 91 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 43: 43 = 91 ∗ x 43 = 91*x 43 = 91 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 91: 43 91 = x \frac{43}{91} = x 91 43 ​ = 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 = 0.473 x = 0.473 x = 0.473 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!
