Accepted Solution

A:
75 Divided by What Equals 7? 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 75 by to equal 7? Solving 75 Divided by What Equals 7 Here’s how you would set up this question as an equation: 75 x = 7 \frac{75}{x} = 7 x 75 ​ = 7 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 75: 75 = 7 ∗ x 75 = 7*x 75 = 7 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 7: 75 7 = x \frac{75}{7} = x 7 75 ​ = 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 = 10.714 x = 10.714 x = 10.714 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!
