Kto to umie rozwiązać ? Oblicz pamiętając o skaracaniu : 3/5 x 1/8 x 10/3 = 3/7 x 14/15 x 10/21= 5/12 x 9/40 x 8/15 = 15/27 x 12/25 x 5/24 = 46/39 x 3/8 x 13/23 =  

3/5 x 1/8 x 3 1/3 = 1/5 x 3 1/3 = 3 1/15  

3/5 x 1/8 x 10/3 =1 x1/8 x 2=1/4 3/7 x 14/15 x 10/21=1x2/3 x 2/7=4/21 5/12 x 9/40 x 8/15 =1/4 x 3/5 x 1/3=3/60=1/20 15/27 x 12/25 x 5/24 =3/9 x 4/5 x 5/24= 1/9 x 4/5 x 5/8= 1/9 x 1/5 x 5/2= 5/90=1/18 46/39 x 3/8 x 13/23 = 2/3 x 3/8 x 1= 6/24=1/4
