Guided Notes
3 key concepts
- 1
When multiplying fractions, we multiply the numerators to get the new numerator, and multiply the denominators to get the new denominator.
- 2
2/3 × 4/5 means we are trying to find 4/5 of 2/3, or 2/3 of 4/5.
- 3
Splitting each third into five parts results in 15ths, because 3 multiplied by 5 is 15.
