Szczegółowe wyjaśnienie:a) 11/6 * 3/11 * 8/7 = 4/7
b) 1/8 * 8/3 * 6/7 = 2/7
c) 5/6 * 6 - 3 * 5/6 = 5 - 5/2 = 2,5
d) (35/8 - 5/3) * 4/15 = (35*3-5*8)/24 * 4/15 = 65/24 * 4/15 = 13/18
e) 11/5 - 7/6 *3/7 = 11/5 - 1/2 = (22-5)/10 = 17/10 = 1,7
f) (99+4)/24 * 4/13) - 1/27 = 13/24 * 4/13 - 1/27 = 1/6 - 1/27 = (9-2)/54 = 7/57
g) 5/8 * 3/5 +9/5 * 5/6 -5/9 * (7/4 - 2/5) + 11/6 = 3/8 + 3/2 -5/9 * 27/20 - 11/6 =
= 3/8 + 3/2 - 3/4 +11/6 = (9+36-18+44)/24 = 71/24
h) 4/3 * 5/4 - 3/2 * 5/6 + 9/8 : (9/8 - 3/4) +11/6 = 5/3 - 5/4 + 9/8 : ((9-6)/8) + 11/6 =
5/3 - 5/4 + 9/8 * 8/3 + 11/6 = 3 + 5/3 - 5/4 + 11/6 = 3 + (20-15+22)/12 = 3 27/12 = 5 3/12
= 5 1/4
