Explicație pas cu pas:
a) 7/6 - 2/3 = 7/6 - 4/6 = 3/6 = 1/2
b) 36/15 - 7/5 = 36/15 - 21/15 = 15/15 = 1
c) 17/12 - 7/6 = 17/12 - 14/12 = 3/12 = 1/4
d) 25/18 - 5/9 = 25/18 - 10/18 = 15/18 = 5/6
e) 14/3 - 7/6 = 28/6 - 7/6 = 21/6 = 7/2
f) 59/18 - 19/9 = 59/18 - 38/18 = 21/18 = 7/6
g) 116/15 - 11/5 = 116/15 - 33/15 = 83/15
h) 39/4 - 187/20 = 195/20 - 187/20 = 8/20 = 2/5
i) 35/6 - 4/3 = 35/6 - 8/6 = 27/6 = 9/2
j) 80/9 - 8/3 = 80/9 - 24/9 = 56/9
k) 116/15 - 37/5 = 116/15 - 111/15 = 5/15 = 1/3
l) 233/24 - 37/4 = 233/24 - 222/24 = 11/24
