+
= <u>11/12</u>
17) 1/2 + 2/5 = 5/10 + 4/10 = <u>9/10</u>
18) 3/10 + 4/5 = 3/10 + 8/10 = <u>11/10</u>
19) 3/4 + 3/8 = 6/8 + 3/8 = <u>9/8</u>
20) 2/7 + 1/2 = 4/14 + 7/14 = <u>11/14</u>
21) 1/6 + 3/4 = 2/12 + 9/12 = <u>11/12</u>
22) 10/15 + 2/5 = 10/15 + 6/15 = <u>16/15</u>
23) 1/2 + 4/9 = 9/18 + 8/18 = <u>17/18</u>
24) 2/3 + 3/5 = 10/15 + 9/15 = <u>19/15</u>
25) 3/4 + 3/12 = 9/12 + 3/12 = 12/12 = <u>1</u>
26) 5/6 + 1/18 = 15/18 + 1/18 = 16/18 = <u>8/9</u>
27) 1/3 + 5/6 = 2/6 + 5/6 = <u>7/6</u>
28) 3/4 + 5/6 = 9/12 + 10/12 = <u>19/12</u>
29) 1/3 + 2/7 = 7/21 + 6/21 = <u>13/21</u>
30) 5/12 + 3/8 = 10/24 + 9/24 = <u>19/24</u>
31) 3/5 + 1/6 = 18/30 + 5/30 = <u>23/30</u>
