11 plus 5-10 plus 20-9 plus 14-10 is equal to 21
2/3 + 2/7 = 14/21 + 6/21 = 20/21
-8+(-21) = -29
(-44) + (-21) = -65
2/3 +4/7 = 14/21 + 12/21 = 26/21 = 1 5/21
It is 20/21 . because 2/3 equal 14/21 , 2/7 equal 6/21 . 14/21+6/21= 20/21
The sum of 3/14 and 13/21 is 5/6.
7/8 + 14/8 = 21/8
11 plus 5-10 plus 20-9 plus 14-10 is equal to 21
2/3 + 2/7 = 14/21 + 6/21 = 20/21
-8+(-21) = -29
(-44) + (-21) = -65
2/3 +4/7 = 14/21 + 12/21 = 26/21 = 1 5/21

-21
21 + 21 = 42.
it would be 21. I think the answer is -22. Because -16 + -21= -37 + 15= -22
