Szczegółowe wyjaśnienie:
1.
a) 2222 11/117 : 4444 22/117 =
= (259974/117 + 11/117) : (519948/117 + 22/117) =
= (259985/117) : (519970/117) = (259985/117) • (117/519970) =
= 259985/519970 = 1/2
b) 133 5/222:399 15/222 =
= (29526/222 + 5/222) : (88578/222 + 15/222)=
= (29531/222) : (88593/222) =
= 29531/222 • 222/88593 = 1/3
c) ( 222•17/17 + 4/17) : ( 333•17/17 + 6/17) =
= 3774/17 + 4/17) : (5661/17 + 6/17) =
= (5778/17) : (5667/17) = (5778/17)•17/5667 =
= 5778/5667 = 1,019587083112
d) 4 231/1000:12 693/1000 =
(4000/1000 + 231/1000):(12000/1000 + 693/1000) =
= (4231/1000) : (12693/1000) =
(4231/1000)(1000/12693) = 1/3
