1/5 + 3/10 = 2/10 + 3/10 = 5/10 = 1/2
1/4 + 5/8 = 2/8 + 5/8 = 7/8
1/3 + 4/9 = 3/9 + 4/9 = 7/9
1 i 1/6 + 3 i 5/12 = 1 i 2/12 + 3 i 5/12 = 4 i 7/12
odejmowanie:
3/5 - 3/10 = 6/10 - 3/10 = 3/10
7/3 - 7/9 = 21/9 - 7/9 = 14/9 = 1 i 5/9
3 i 1/2 - 1/4 = 3 i 2/4 - 1/4 = 3 i 1/4
5 i 1/3 - 1 i 1/6 = 5 i 2/6 - 1 i 1/6 = 4 i 1/6
1/5+3/10=2/10+3/10=5/10=1/2
1/4+5/8=7/8
1/3+4/9=3/9+4/9=7/9
1 1/6+3 5/12= 1 2/12+3 5/12= 4 7/12
odejmowanie:
3/5-3/10= 6/1/-3/10=3/10
7/3-7/9= 21/9-7/9= 14/9=1 5/9
3 1/2-1/4=7/2-1/4=14/4-1/4=13/4=3 1/4
5 1/3-1 1/6=5 2/6-1 1/6=4 1/6
licze na naj.
mam nadzieje że pomogłam <3
