a) 2/14 + 5/14 = 7/14 = ½
b) 9/12 +5/12 = 14/12 = 1 2/12 = 1⅙
c) 16/18 - 5/18 = 11/18
d) 4/12 + 9/12 = 13/12 = 1 1/12
e) 6/10 - 5/10 = 1/10
f) 3/2 - 1/3 = 9/6 - 2/6 = 7/6 = 1 ⅙
g)3/2 + 3/8 = 12/8 + 3/8 = 15/8 = 1 ⅞
h) 4/3 - 2/9 = 12/9 - 2/9 = 10/9 = 1 1/9
i) 13/5 - 7/10 = 26/10 - 7/10 = 19/10 = 1 9/10
j) ⅚- ¼ = 10/12 - 3/12 = 7/12
k)7/6 - 7/9 = 21/18 - 14/18 = 7/18
l) 19/8 - 11/6 = 57/24 - 44/24 = 13/24
Mam nadzieje że pomogłam^^
