- First make the denominators the same by multiplying the denominators together, or finding the number that they can both go into.
- Add numerator to numerator and denominator to denominator
- You could simplify if the numerator and denominator are not prime numbers
SUBTRACTING FRACTIONS:
- First make the denominators the same by multiplying the denominators together, or finding the number that they can both go into.- Subtract numerator to numerator and denominator to denominator
- You could simplify if the numerator and denominator are not prime numbers
MULTIPLYING FRACTIONS:
Multiplying proper fractions:- Multiply numerator to numerator and denominator to denominator
- Simplify if answer is not a prime number
Multiplying mixed fractions:
- Convert mixed fractions to improper fractions
- Multiply numerator to numerator and denominator to denominator
- Simplify if answer is not a prime number
DIVIDING FRACTIONS:
- First you must find the reciprical. The reciprical is one of the fractions upside down.- Multiply the numerators and denominators
- Convert the fraction into mixed fractions
- Simplify if answer is not a prime number
Dividing mixed fractions:
- Convert mixed fractions into improper fractions- BE THE BULLY
- Find the reciprical
- Multiply numerator to numerator and denominators to denominators
- Convert answer to mixed fraction
WORD PROBLEMS:
