  • B. 0.375 & 1
  • C. 13.75 & 1.1
  • D. 0.375 & 0.1

  • Correct Answer
  • 0.375 & 0.1 

    Explanation

    3/8 as a Decimal :

    In this we should convert the denominator into 10, 100, 1000, 10000, 100000,... to make it simple.

    Now to make 8 into 1000, we multiply numerator and denominator with 125

    =>  3   x   125 8   x   125   =   375 1000   =   0 . 375

     

    1/10 as a Decimal :

    1 divided into 10 parts of each 0.1.

     

    Therefore, 3/8 = 0.375 and 1/10 = 0.1 in decimals.
