Odpowiedź:
a) 1/4(12/7+66/14)= 1/4(24/14+66/14)=1/4(90/14)=90/56=1 34/56=1 17/28
b) 3 2/3[(1/3-1/24)•8]= 11/3[(8/24-1/24)•8=11/3[7/24•8]=11/3•56/24=168/24=7
a)
4 * 3/7 + 11/14 * 6 = 4/1 * 3/7 + 11/14 * 6/1 = 12/7 + 33/7 = 45/7
1/4 * 45/7 = 45/28 = 1 17/28
b)
(1/3 - 1/24) * 8 = (8/24 - 1/24) * 8 = 7/24 * 8/1 = 7/3
3 2/3 = 11/3
11/3 * 7/3 = 77/9 = 8 5/9
