This tutorial is intended to guide you on how to solve division equations where only one factor is known. This kind of problem requires solving for the unknown, which often represented by the variable "x".
Let's take an example: "What divided by 2 equals 79?". In this statement, "what" is the unknown factor we need to find. We can rewrite this problem as a mathematical statement using a variable, such as: x/2 = 79.
That gives us a simple equation to solve. To isolate x, we just multiply both sides of the equation by 2 to give us: x = 79 * 2.
Computing the right side of the equation, we find: x = 158.
Let's check if 158 is the correct answer by substitizing it back into the original problem: 158/2 = 79. Since this statement is true, 158 is the correct answer.
To build up your skills in finding an unknown factor, here are some other problems to consider:
- What divided by 7 equals 4?
- 9 divided by what equals 89?
- What is 10/8 divided by 50?
- What is 17/9 divided by 12/19?
- What is 27 divided by 4/20?
Equations of this sort are solved in a similar way: Divide or multiply both sides in order to isolate the unknown factor.
