Adding and Subtracting Fractions with Unlike Denominators

The student will be able to:

• Find a common denominator by multiplying the denominators together.
• Rename fractions using their least common denominator.
• Identify the LCD of two or more fractions.
• Add fractions with unlike denominators by converting to equivalent fractions with a LCD.
• Simplify the result when necessary.
• Recognize that the numerator and the denominator of a fraction must be multiplied by the same nonzero whole number in order to have equivalent fractions.
• Recognize that there are two methods for adding and subtracting fractions with unlike denominators: common denominators and LCD.
• Describe the procedure for each method of adding and subtracting fractions with unlike denominators.
• Add and subtract fractions with unlike denominators by applying one the procedures above.
• Apply procedures to complete five interactive exercises.

Adding Mixed Numbers

The student will be able to:

• Define mixed numbers.
• Describe the procedure for adding mixed numbers.
• Recognize that a mixed number consists of a whole-number part and a fractional part.
• Recognize that it is easier to arrange the work vertically in order to add mixed numbers.
• Find the sum of two mixed numbers by applying the procedure for adding mixed numbers.
• Find the sum of a mixed number and a whole number by applying the procedure for adding mixed numbers.
• Simplify the result when necessary.
• Apply the procedure to complete five interactive exercises.

Subtracting Mixed Numbers

The student will be able to:

• Identify the whole-number part and the fractional part of a mixed number.
• Describe the procedure for subtracting mixed numbers with like denominators.
• Borrow a mixed number by converting it to an improper fraction.
• Describe the procedure for subtracting mixed numbers with unlike denominators.
• Subtract mixed numbers with like and unlike denominators by following the procedures presented.
• Subtract a mixed number from a whole number by following the procedures presented.
• Subtract a whole number from a mixed number by following the procedures presented.
• Recognize that there is another way to subtract mixed numbers is to convert each mixed number into an improper fraction.
• Recognize subtract mixed numbers by convert each mixed number into an improper fraction can lead to careless errors.
• Solve a real-world problem by subtracting mixed numbers.
• Apply procedures to complete five interactive exercises.
