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

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

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

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