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

Express the following as improper fractions: (a) (7)(3)/(4) (b) (5)(6)/(7) (c) (2)(5)/(6) (d) (10)(3)/(5) (e) (9) (3)/(7) (f) (8)(9)/(4)

1(3)/(4)-1(1)/(5)+1(5)/(8)=?( a) 2(7)/(40) (b) (7)/(40) (c) 9(5)/(8)(d)10(7)/(8) (e) None of these

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

The arrangement of rational numbers (-7)/(10),(5)/(-8),(2)/(-3) in ascending order is (2)/(-3),(5)/(-8),(-7)/(10) (b) (5)/(-8),(-7)/(10),(2)/(-3) (c) (-7)/(10),(5)/(-8),(2)/(-3)(d)(-7)/(10),(2)/(-3),(5)/(-8)

Write the set {(1)/(2),(2)/(3),(3)/(4),(4)/(5),(5)/(6),(6)/(7),(7)/(8),(8)/(9),(9)/(10)} in the set builder form.

Convert each of the following Into an improper fraction: (i) 5(5)/(7) (ii) 9(3)/(8) (iii) 6(3)/(10) (iv) 3(5)/(11) (v) 10(9)/(14) (vi) 12(7)/(15) (vii) 8(8)/(13) (viii) 51(2)/(3)
