Add and subtract mixed numbers

key notes:

1. What is a Mixed Number?

• A mixed number consists of a whole number and a fraction.
  • Example: 3×1/4 (3 is the whole number, 1/4​ is the fraction).

2. Steps for Adding Mixed Numbers:

• Step 1: If the fractions have the same denominator, add the fractions first. If not, find a common denominator.
• Step 2: Add the whole numbers separately.
• Step 3: Combine the sum of the whole numbers with the sum of the fractions.
• Step 4: If the fraction sum is greater than 1, convert the improper fraction into a mixed number and add it to the whole number sum.
• Step 5: Simplify the final answer, if necessary.

3. Steps for Subtracting Mixed Numbers:

• Step 1: If the fractions have the same denominator, subtract the fractions first. If not, find a common denominator.
• Step 2: Subtract the whole numbers separately.
• Step 3: If the fraction from the second mixed number is greater than the fraction from the first mixed number, borrow 1 from the whole number and convert it into a fraction with the same denominator.
• Step 4: Combine the whole number difference with the fraction difference.
• Step 5: Simplify the final answer, if necessary.
