One mole of TMGHC (Trimethylglycine Hydrochloride) contains exactly one mole of Glycine, so you simply convert 648mg to moles of TMGHC then convert back to mass of Glycine.
[eqn] \text{Number of moles in X} = \frac{\text{Mass of X}}{\text{Molar mass of X}} [/eqn]
So 648 mg of TMGHC is [math] \frac{0.648}{153.607} = 0.004218557748 \text{ moles} [/math] and this is the same number of moles of Glycine so we convert back to mass of Glycine, so 0.004218557748 moles of Glycine is [math] 0.004218557748 \cdot 75.067 = 0.317 \text{ grams} [/math] or 317 mg.

For that you simply divide the molar mass of Glycine by the molar mass of TMGHC so [math] \frac{75.067}{153.607} = 0.4887 = 48.87\%[/math] So 48.87% of TMGHC is Glycine by mass.
