  1. (i) 13/3125

    ncert solutions class 10 chapter 1-3

    13/3125 = 0.00416

    (ii) 17/8

    ncert solutions class 10 chapter 1-4

    17/8 = 2.125

    (iii) 64/455 has a Non terminating decimal expansion

    (iv)15/ 1600

    ncert solutions class 10 chapter 1-5

    15/1600 = 0.009375

    (v) 29/ 343 has a Non terminating decimal expansion

    (vi)23/ (2352) = 23/(8×25)= 23/200

    ncert solutions class 10 chapter 1-6

    23/ (2352) = 0.115

    (vii) 129/ (225775) has a Non terminating decimal expansion

    (viii) 6/15 = 2/5

    ncert solutions class 10 chapter 1-7

    (ix) 35/50 = 7/10

    ncert solutions class 10 chapter 1-8

    35/50 = 0.7

    (x) 77/210 has a non-terminating decimal expansion.
