a) 4/9*3/4 = 1/3
b) 5/8*7/12 = 35/96
c) 7/8*24/33 = 7/11
d) 1i 1/8*4/15 = 9/8 * 4/15 = 3/10
e) 2i 3/5:5 = 13/5 : 5 = 13/5 * 1/5 = 13/25
f) 1i 5/7:6 = 12/7 : 6 = 12/7 * 1/6 = 2/7
g) 6i 1/2:3 i 1/4 = 13/2 : 13/4 = 13/2 * 4/13 = 2
h) 7i 1/3 : 2 i 2/5 = 22/3 : 12/5 = 22/3 * 5/12 = 55/36 = 1 i 19/36
i) 2*13/4 13/2
--------- = ---------- = 13/2 : 8 = 13/2 * 1/8 = 13/16
8 8
Mam nadzieję że pomogłam ;)
