Grade 5 Fractions and Ratios CCSS: 5.NF.A.2, MP2, MP7

A bird watcher observes a bird flying at a height of $6/10$ kilometer. The bird dives down toward the ground then continues flying at a height $2/5$ kilometer below its original height.

The bird watcher states that the bird is now flying at a height of $4/5$ kilometer.

Which TWO statements are true?
1. Since $6/10$ minus $2/5$ is $4/5$, the height is reasonable.
2. Since $4/5$ is greater than $6/10$, the height is not reasonable.
3. The fraction $2/5$ is $4/10$, and $4/10$ equals $4/5$, so the height is reasonable.
4. The fraction $2/5$ is $4/10$, and $6/10$ minus $4/10$ does not equal $4/5$, so the height is not reasonable.
5. The fraction $2/5$ is $4/10$, and $6/10$ plus $4/10$ is less than $4/5$, so the height is not reasonable.
