Learning Objective
I can solve real-world problems by adding fractions and mixed numbers.
- 1
When adding mixed numbers with like denominators, first add the whole numbers, then add the numerators, keeping the same denominator.
- 2
If adding mixed numbers results in an improper fraction, convert the improper fraction to a proper fraction and add it to the whole number.
- 3
When subtracting mixed numbers, you may need to borrow from the whole number if the numerator in the second fraction is greater than the numerator in the first fraction.
