Odpowiedź :
a) 5/10 - 1/3= 15/30 - 10/30= 5/30= 1/6
b) 5/6 - 1/8= 20/24 - 3/24= 17/24
a) 3/5*5/12= 15/60= 1/4
b) 4/7 * 7/25 = 28/175
a) 2/5 : 2/5 = 1
b) 6/25 : 3/5 = 6/25 * 5/3 = 30/75 = 6/15
b) 5/6 - 1/8= 20/24 - 3/24= 17/24
a) 3/5*5/12= 15/60= 1/4
b) 4/7 * 7/25 = 28/175
a) 2/5 : 2/5 = 1
b) 6/25 : 3/5 = 6/25 * 5/3 = 30/75 = 6/15
a,)5/10-1/3=1/2-1/3=3/6-2/6=1/6
b) 5/6-0,125=5/6-1/8=40/48-6/48=34/48
a)0,6×5/12=6/10×5/12=1/4
b)4/7×0,28=4/7×28/100=4/7×7/25=4/25
a)0,4:2/5=2/5×5/2=1
b)6/25÷0,6=6/25×5/3=2/5
