pomóżcie wykonać odejmowanie i sprawdzić za pomocą dodawania. a) 8,53 - 0,856 b) 18,753 - 17,86 c) 37,8 - 18,921
a)
8,530 - 0,856 = 7,674
spr.
7,674 + 0,856 = 8,530
b)
18,753 - 17,860 = 0,893
17,860 + 0,893 = 17,860
c)
37,800 - 18,921 = 18,879
18,879 - 18,921 = 37,800
Dawanie naj działa na dobre wszystkim. Korzystaj! ;)
Spr: 7,674 + 0,856 = 8,530
Spr: 0,893 + 17,830 = 18,753
Spr: 18,879 + 18,921 = 37,800
