A:
78 Divided by What Equals 56? 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 78 by to equal 56? Solving 78 Divided by What Equals 56 Here’s how you would set up this question as an equation: 78 x = 56 \frac{78}{x} = 56 x 78 ​ = 56 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 78: 78 = 56 ∗ x 78 = 56*x 78 = 56 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 56: 78 56 = x \frac{78}{56} = x 56 78 ​ = 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 = 1.393 x = 1.393 x = 1.393 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!
