Adding and subtracting fractions involves working with numbers that represent parts of a whole. To add fractions, first ensure they have a common denominator by finding the least common multiple of the denominators. For example, to add 1/4 and 1/2, convert 1/2 to 2/4, then add the numerators: 1/4 + 2/4 = 3/4.
To subtract fractions, also use a common denominator. For instance, to subtract 1/3 from 2/3, the common denominator is 3, so 2/3 – 1/3 = 1/3. If the fractions don’t have the same denominator, like 3/4 – 1/5, find a common denominator (which is 20), convert to 15/20 – 4/20, and subtract: 15/20 – 4/20 = 11/20.
Remember, always simplify the result if possible, such as reducing 10/20 to 1/2. This process helps in solving problems in math, cooking, and everyday measurements.
