Answer 1

42.31 → 42.49

Explanation:

range of h rounded to 47.2: 47.15 → 47.24

range of k rounded to 4.8: 4.75 → 4.84

lower bound of h - k: 47.15 - 4.84 = 42.31

upper bound of h - k: 47.24 - 4.75 = 42.49

42.31 → 42.49

47.2 - 4.8 = 42.4

lower and upper range of h - k can also be expressed as:

42.4 ± 0.09
