Answer 1

a) 5 hg ... 500 g
175 mg ... 0,175 g
2,5 dag ...25 g
500+0,175-25 = 500,175 - 25 = 475,175
b) 1 h 25 min ... 5100 s
43 min 20 s ... 2600 s
1 h 10 min 13 s ... 4393 s
5100 + 2600 - 4393 = 7700 - 4393 = 3307 s.

500+0,175-25 = 500,175 - 25 = 475,175 grame

5100 + 2600 - 4393 = 7700 - 4393 = 3307 secunde
