Example & extra help
Try a sample

- They are equally long.
- B
- A
- Their colors decide.
See the answer & why
A
8 is greater than 5, so ribbon A is longer when both use the same unit.
A little hint: Line up one end and use the same size measuring unit for both lengths.
Line up the objects at one end, or measure both with identical blocks.
