" (viii) "(6)/(15)

Find the HCF of ( 5)/( 6), ( 15)/( 8) and ( 25)/( 32)

Simplify: ((3)/(11)x(5)/(6))-((9)/(12)x(4)/(3))+((5)/(13)x(6)/(15))

Compare (5)/(6) and (13)/(15)

Using laws of exponents, simplify and write the answer in exponential from: (i) 6^(15)-:6^(10) (ii) (5^3)^2

(4)/(15)+(6)/(35)

((15),(8))+((15),(9))-((15),(6))-((15),(7))=......

""^(15)C_(9)-_""^(15)C_(6)+""^(15)C_(7)-^(15)C_(8) equals to
