Answer 1

3 6/9 - 2 2/6 = 33/9 - 14/6 = 66/18 - 42/18
= 24/18 : 2/2 = 12/9 : 3/3 = 4/3
= 1 1/3

4/5 - 1/10 - 1/2 = 8/10 - 1/10 - 5/10 = 2/10 : 2/2
= 1/5

1 4/5 - 2/3 - 1/2 = 9/5 - 2/3 - 1/2
= 54/30 - 20/30 - 15/30
= 19/30

2 2/5 - 1 1/4 - 1/3 = 12/5 - 5/4 - 1/3
= 144/60 - 75/60 - 20/30
= 49/60

4 8/9 - 2 1/6 - 1 1/3 = 44/9 - 13/6 - 4/3
= 88/18 - 39/18 - 24/18
= 25/18 = 1 7/18

0,7 - 0,26 = 7/10 - 26/100 = 70/100 - 26/100
= 44/100 = 0,44

0,73 - 0,432 = 73/100 - 432/1000
= 730/1000 - 432/1000
= 298/100 = 2,98
