Y=1/3, poniewaz 2/3 razy ile to 2/9=1/3
Przykladu z nie widac.
12 × 3/4 = 36/4 = 9
8/5 × 3/4 = 24/20 = 1 4/20 = 1 1/5
14/15 × 3/4 = 54/60 = 27/30
7/6 × 3/4 = 21/24
8/3 × 3/4 = 24/12 = 2
Mam nadzieje, ze pomoglam :)))
1/2 *x=3/20
x=3/20*5/1
x=3/4
2/3 *y=2/9
y=2/9*3/2
y=1/3
11
3/4*12/1=9
3/4*8/5=6/5=1 1/5
3/4*14/15=14/20=7/10
3/4*1 1/6=3/4 *7/6=7/8
3/4 *2 2/3=3/4*8/3=2
reszta jest ucięta
