Find: `3/7+\ (-6/(11))+8/(21)+\ ((-5)/(22))`

Solve using properties : (a) (3)/(7)+((-6)/(11))+((-8)/(21))+(5)/(25)

If (3)/(7) + x +((-8)/(21)) +(5)/(22) =(-125)/(462) , then x is

The expression (5(5)/(8))/(6(3)/(7)) of (6(7)/(11))/(9(1)/(8))-:(8)/(9)(2(3)/(11)+(13)/(22)) of (3)/(5) equals (a) 1 (b) (1)/(2)( c) (7)/(9)( d) (5)/(12)

Find the difference: 6/7-9/(11) (ii) 8-5/9

Find the missing number (11)/(2),(5)/(8),(7)/(3) , ?

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)

Find (i) (7)/(24)-(17)/(36) (ii) (5)/(63)-((-6)/(21))( iii) (-6)/(13)-(7)/(11)(v)(-2)(1)/(9)-6

Find the sum: (5)/(6)+(7)/(8)+(11)/(12)
