1 + 1/2 = 2/2 + 1/2 = 3/2 = 1 1/2 = 1 5/10 = 1,5
2 - 3/4 = 1 4/4 - 3/4 = 1 1/4 = 1 25/100 = 1,25
3 * 2/5 = 6/5 = 1 1/5 = 1 2/10 = 1,2
4 : 3/4 = 4 * 4/3 = 16/3 = 5 1/3 = 5,3333... = 5,(3)

1/2 : 3/4 = 1/2 * 4/3 = 1 * 2/3 = 2/3 = 0,6666.... = 0,(6)
1/3: 2= 1/3 * 1/2 = 1/6 = 0,16666... = 0,1(6)
Odpowiedź:
Szczegółowe wyjaśnienie:
1+ 1/2=1 1/2
2- 3/4=1 4/4 -3/4=1 1/4
3* 2/5==6/5=1 1/5
4: 3/4=4 *4/3=16/3=5 1/3
7- 6/8=6 8/8 -6/8=6 2/8=6 1/4
2+1 1/3=3 1/3
9 -6 3/4=8 4/4 -6 3/4=2 1/4
1/2 : 3/4=1/2*4/3=2/3
1/3 : 2= 1/3*1/2=1/6
