    Answer:

    \frac{1}{3}

    Step-by-step explanation:

    We require the quantities to have the same dimensions.

    Using the conversion

    1 metre = 100 cm, then

    2.1 m = 2.1 × 100 = 210 cm

    The fraction can then be expressed as

    *** QuickLaTeX cannot compile formula:
    \frac{70}{210}
    
    *** Error message:

    ← divide numerator/ denominator by 70

    = \frac{1}{3} ← in simplest form
