निम्न परिमेय संख्या को दशमलव रूप में बदलो- (3)/(5),(4)/(25),(7)/(10),(-13)/(125),(9)/(40). | 7 ...

2 3/5-:5/7=\ (13)/7 (b) (13)/(25) (91)/(25) (d) (25)/(91)

Simplify :(-3)/(10)+(7)/(15)+(3)/(-20)+(-9)/(10)+(13)/(15)+(13)/(-20)

Simplify: (-3)/(10)+(7)/(15)+(3)/(-20)+(-9)/(10)+(13)/(15)+(13)/(-20)

(9)/(7)times(3)/(5)+(8)/(7)-(9)/(7)times(10)/(9)

3(5a-7)-2(9a-11)=4(8-13-1)

{:(4,12,11,5),(6,7,10,3),(8,9,10,7),(7,5,?,4):}
