A:
51 Divided by What Equals 65? 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 51 by to equal 65? Solving 51 Divided by What Equals 65 Here’s how you would set up this question as an equation: 51 x = 65 \frac{51}{x} = 65 x 51 ​ = 65 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 51: 51 = 65 ∗ x 51 = 65*x 51 = 65 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 65: 51 65 = x \frac{51}{65} = x 65 51 ​ = 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 = 0.785 x = 0.785 x = 0.785 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!
