Accepted Solution

A:
70 Divided by What Equals 9? 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 70 by to equal 9? Solving 70 Divided by What Equals 9 Here’s how you would set up this question as an equation: 70 x = 9 \frac{70}{x} = 9 x 70 ​ = 9 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 70: 70 = 9 ∗ x 70 = 9*x 70 = 9 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 9: 70 9 = x \frac{70}{9} = x 9 70 ​ = 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 = 7.778 x = 7.778 x = 7.778 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!
