![]() ![]() The “Reciprocal of a fraction is that fraction turned “upside down”. The following video covers both Division and Multiplication Equations.Įquations like 5n/4 = 10 can be solved by multiplying both sides by the reciprocal of 5/4. Here is a great video all about Division Equations. Here is an example of how to solve a typical Division Equation. ![]() To solve a Division equation, we MULTIPLY BOTH SIDES by the number that our variable letter is being divided by. The Opposite of Division is Multiplication. If our variable letter has a number directly under it as a fraction, then this means it is divided by that number. Here is a detailed video from Khan Academy about how multiplication by grouping actually works. Here is a more comprehensive video, that includes using a balance beam to represent the equation and solve it. The following short video shows how to do a Multiplication Equation. ![]() Here is an example of how to solve a typical Multiplication Equation. To solve a multiplication equation, we DIVIDE BOTH SIDES by whatever number is in front of our variable letter. ![]() The Opposite of Multiplication is Division. If our variable letter has a number directly in front of it, then this means it is multiplied by that number. Here are some reminder examples of how to do Addition and Subtraction Equations. These have already been covered in separate lessons on our blog.Ĭlick the links below to visit these lessons. Solving Addition and Subtraction Equations The different types of one step equations and their opposites are shown below. One step equations require one “opposite” operation to be performed on them, which then allows us to obtain the value of their unknown variable. ![]()
