" (iii) `((-2)/(5)+(4)/(7))+((-2)/(5)) ( iv )(3)/(4)+(7)/(6)+((-5)/(4))+(1)/(2)`

(7)/(8)-:(7(1)/(2)-5(1)/(6)-:2(3)/(4))+4(1)/(2)

(-3)/(4)+((2)/(5)+(-4)/(7))=((-3)/(4)+(2)/(5))+((-4)/(7))

Solve (i) 2-(3)/(5)(ii)4+(7)/(8)(iii)(3)/(5)+(2)/(7)(iv)(9)/(11)-(4)/(5)(v)(7)/(10)+(2)/(5)+(3)/(2)(vi)(2)(2)/(3)+(3)(1)/(2) (vii) (8)(1)/(2)-(3)(5)/(8)

Simplify: (-3)/(2)+(5)/(4)+(7)/(4)( ii) (5)/(3)-(7)/(6)+(-2)/(3)

If A=[(2)/(3)1(5)/(3)(1)/(3)(2)/(3)(4)/(3)(7)/(3)2(2)/(3)] and B=[(2)/(3)(2)/(5)1(1)/(5)(2)/(5)(4)/(5)(4)/(5)(7)/(3)(6)/(5)(2)/(5)], then compute 3A_(-)=5B

Verify the following: (i) ((3)/(4)+(-2)/(5))+(-7)/(10)=(3)/(4)+((-2)/(5)+(-7)/(10)) (ii) ((-7)/(11)+(2)/(-5))+(-13)/(22)=(-7)/(11)+((2)/(-5)+(-13)/(22)) (iii) -1+((-2)/(3)+(-3)/(4))=(-1+(-2)/(3))+(-3)/(4)

Which is greaster: (2)/(7) of (3)/(4) or (3)/(5) of (5)/(8)( ii) (1)/(2) of (6)/(7) or (2)/(3) of (3)/(7)

Find :(i)(7)/(3)-:2(ii)(4)/(9)-:5(iii)(6)/(13)-:7(iv) (4) (1)/(3)-:3(v)(3)(1)/(2)-:4(vi)(4)(3)/(7)-:7

5(1)/(4)+6(2)/(3)+7(1)/(6)=?
