Study Notes

When adding fractions with a common denominator, the common denominator is kept, and the numerators are added together.
To add fractions with different denominators, a common denominator must be found, which can be done by listing the multiples of each denominator and finding the smallest number in common.
The lowest common denominator is used to make the denominator of both fractions the same.
To make equivalent fractions with a different denominator, both the numerator and denominator of the original fraction must be multiplied or divided by the same number.
For example, one fourth can be rewritten as an equivalent fraction with a denominator of eight by multiplying both the numerator and denominator by two, resulting in two eighths.
Once fractions have a common denominator, they can be added by keeping the common denominator and adding the numerators.
The rules for subtracting fractions are the same as for adding, requiring a common denominator to be found before subtracting the numerators.
When finding a common denominator, the lowest multiple that both denominators have in common is used.
Equivalent fractions can be created by multiplying or dividing both the numerator and denominator by the same number.
After adding or subtracting fractions, the resulting fraction should be checked for simplification by finding any numbers that divide evenly into both the numerator and denominator.
Simplification is done by dividing both the numerator and denominator by the common number to get a reduced equivalent fraction.
