    First we should convert the grams into mg... 1 gram = 1000 mg 17 g = 17,000mg 5 g = 5,000mg

    And then you can subtract 17,000mg - 5,000mg

    \[ \frac{5}{17} = \frac{x}{10500} \]

    I would multiply both sides by 10500 \[ \frac{5}{17}\cdot 10500 = \frac{x}{10500}\cdot 10500 \]

    on the right side , 10500/10500 simplifies to 1 and 1*x is x the left side will be the answer in milligrams
