Accepted Solution

A:
7 Divided by What Equals 55? 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 7 by to equal 55? Solving 7 Divided by What Equals 55 Here’s how you would set up this question as an equation: 7 x = 55 \frac{7}{x} = 55 x 7 ​ = 55 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 7: 7 = 55 ∗ x 7 = 55*x 7 = 55 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 55: 7 55 = x \frac{7}{55} = x 55 7 ​ = 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 = 0.127 x = 0.127 x = 0.127 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!
