Find the least common multiple of two whole numbers less than or equal to 12 to add and subtract fractions with unlike denominators
Add or subtract each fraction using the least common multiple to create like denominators. Write your answers as improper fractions.
Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1-100 with a common factor as a multiple of a sum of two whole numbers with no common factor. For example, express 36 + 8 as 4 (9 + 2)..
