Fractions

1. Addition&Subtraction

1.1. Find the lowest common multiple (LCM) of the fractions to ensure equivalent fractions

1.1.1. Then add or subtract the numerators, while keeping the same denominator for your final answer

2. Multiplication

2.1. When multiplying fractions by whole numbers, write whole numbers over 1

2.2. When multiplying 2 fractions; multiply both the numerators and denominators

3. Division

3.1. Cross multiply

3.2. Find the common reciprocal (flip the numerator and denominator of the second fraction then follow multiplication rules

4. Reduction

4.1. Find the smallest or lowest common denominator(LCD), and apply to both numerator and denominator

4.1.1. All answers should be reduced into lowest terms Ex: 4/8 = 1/2

5. Improper

5.1. When the numerator is larger than the denominator it can stay written improperly, or in another form:

5.1.1. Mixed Number

5.1.1.1. The amount of times the denominator can fit into the numerator, remaining numbers are then displayed beside the whole number in a fraction. Ex: 256/7= 36 and 4/7

5.1.1.1.1. When the fraction is displayed as a mixed number, it is in proper form

6. Equivalent Fractions

6.1. Find the lowest common denominator (LCD) of the fractions to perform operations easier
