    14/8

    B.

    1.75

    C.

    7/4

    D.

    1.7

    Correct option is D

    Given
    Mixed fraction = 1341\frac{3}{4}​​

    Formula Used
    Mixed to improper fraction conversion: abc=a×c+bca\frac{b}{c} = \frac{a × c + b}{c}​​
    Fraction to decimal conversion.

    Solution
    Convert 134 1\frac{3}{4}​ into an improper fraction:

    134=1×4+34=741\frac{3}{4} = \frac{1 × 4 + 3}{4} = \frac{7}{4}​​

    Convert  74\frac{7}{4}​ to an equivalent fraction by multiplying the numerator and denominator by 2:
    7×24×2=148\frac{7 × 2}{4 × 2} = \frac{14}{8}​​
    Convert 74 \frac{7}{4}​ to a decimal:
    74=1.75\frac{7}{4} = 1.75​​
    Comparing with the given options, 1.7 is NOT equal to 134.1\frac{3}{4}.​​
    So the correct answer is (d)
