Key concepts
3 concepts
- 1
When subtracting mixed numbers, it is important to subtract the entire mixed number, including both the whole number and fraction parts.
- 2
When subtracting mixed numbers in stacked form, if the top fraction is smaller than the bottom fraction, you need to borrow or re-group from the whole number part.
- 3
The stacked form is useful for subtracting mixed numbers because it helps to organize the problem and remember that both parts of the mixed number are being subtracted.
