Explicație pas cu pas:

5/18 + 4/18 = 9/18 = 1/2

11/75 + 23/75 + 16/75 = 50/75 = 2/3

23/17 - 3/17 - 5/17 = 14/17

21/20 - 9/20 + 3/20 = 15/20 = 3/4

3 + 1/7 = 21/7 + 1/7 = 22/7

8/5 - 1 = 8/5 - 5/5 = 3/5

4 2/7 + 3 3/7 = 30/7 + 24/7 = 54/7

42 89/100 - 11 39/100 = 4289/100 - 1139/100 = 3150/100 = 126/4 = 63/2

45% + 37% = 82% = 82/100 = 41/50

100% - 13% - 37% = 50% = 50/100 = 1/2
