Adding and Subtracting Fractions with Examples

Study Notes

The text is about adding and subtracting fractions with examples.
Fractions can be added or subtracted if they have the same denominator.
When adding or subtracting fractions with the same denominator, add or subtract the numerators and keep the denominator the same.
When eating 1/4 of a pie and then eating another 1/4, you have eaten 1/2 of the pie.
When adding 2/5 and 1/5, the denominators are the same, so the denominator of the answer is also 5.
When subtracting 3/7 from 2/7, the answer is 1/7.
When adding 1/4 and 1/2, the fractions have different denominators, so the denominators must be made the same before adding.
The smallest number that is a multiple of both 2 and 3 is 6, so both fractions must be converted to have a denominator of 6 before adding.
When subtracting 1/10 from 1, the result is -9/10.
When subtracting -1/9 from -1/4, the least common multiple of 0 and 4 is 36, and the denominators must be multiplied by 9 to make them equal.
The lessons cover adding and subtracting fractions with the same and different denominators.
