To add two mixed numbers, it is necessary:

• to reduce fraction to a least common denominator;
• add the numerators and put the answer over the same denominator;
• simplify the fraction;
• if this fraction is improper then convert fraction to a mixed number;
• add the integer portions of the two mixed numbers;
• if adding the fractional parts created a mixed number then add its integer portion to the sum.

To subtract two mixed numbers, it is necessary:

• to reduce fraction to a least common denominator;
• make the first numerator larger than the second if it is not;
• subtract the second numerator from the first;
• place that difference over the common denominator;
• Subtract the integer portions of the two mixed numbers;
• simplify the fraction.

To multiply mixed numbers, it is necessary:
• converting mixed numbers to improper fractions;
• multiply the numerators and multiply the denominators;
• simplify the fraction;
• if this fraction is improper then convert fraction to a mixed number.

To divide mixed numbers, it is necessary:
• converting mixed numbers to improper fractions;
• to multiply first fraction by reciprocal of second fraction;
• simplify the fraction;
• if this fraction is improper then convert fraction to a mixed number.
