*When multiplying a whole number by a fractions, place the whole number over one and multiply across. Then simplify the answer.
*When multiplying a fraction by a fraction, simply multiply across and then simplify.
* When asked to find the fraction of a number, replace the word “of” with a multiplication sign, place the whole number over one and multiply across. If your answer is an improper fraction, divide and make it a mixed number.
*When we divide fractions, there is ONE rule. It is “Keep, change, flip”. Meaning, we keep the first number or fraction, replace the division sign with a multiplication sign and flip the second fraction. Then multiply across and reduce or make a mixed number if possible.
*When dividing fractions, if one of the numbers is a whole number, place it over one and proceed. The first fraction ALWAYS needs to remain the same because division is not commutative! (6 divided by 3 is NOT the same as 3 divided by 6).
