A:
77 Divided by What Equals 79? 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 77 by to equal 79? Solving 77 Divided by What Equals 79 Here’s how you would set up this question as an equation: 77 x = 79 \frac{77}{x} = 79 x 77 ​ = 79 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 77: 77 = 79 ∗ x 77 = 79*x 77 = 79 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 79: 77 79 = x \frac{77}{79} = x 79 77 ​ = 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 = 0.975 x = 0.975 x = 0.975 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!
