i) -2/3 + 5/7 + 4/3+ -11/7
= -2/3+4/3+5/7+-11/7
= 2/3+-6/7
ii)2/5+ -7/9+ -11/10+ 5/18
= 2/5+-11/10+-7/9+5/18 {Find the LCM of 5,10 = 10 and 9,18 = 18}
2*2/5*2+-11*1/10*1+-7*2/9*2+ 5*1/18*1
= 4/10+-11/10+-14/18+5/18
= -7/10+ - 9/18
= -7/10 + -1/2

Step-by-step explanation:
- 11/3 + -7/6 + -13/4 - 15/8 = -239/24
Step-by-step explanation:
- 11/3 + -7/6 + -13/4 - 15/8
= -11/3 - 7/6 - 13/4 - 15/8
= - ( 11/3 + 7/6 + 13/4 + 15/8)
= - (22/6 + 7/6 + 26/8 + 15/8)
= -(29/6 + 41/8)
= - (116/24 + 123/24)
= - (239/24)
= -239/24
