Calculate one dose for the following drug order. The tablets are scored in half.
Order: amoxicillin 250 mg p.o. b.i.d.
Supply: amoxicillin 0.5 g tablets
Enter the number of tablets you would give.

To calculate the number of tablets required for one dose, let's first convert the supply of amoxicillin tablets from grams to milligrams, so that the units are consistent with the order.

1 gram (g) = 1000 milligrams (mg).  
So, 0.5 grams = 0.5 × 1000 = 500 mg.

**Drug order:** 250 mg  
**Supply:** 500 mg tablets

To calculate the number of tablets needed:

\[
\frac{{\text{{Dose ordered}}}}{{\text{{Dose per tablet}}}} = \frac{{250 \, \text{{mg}}}}{{500 \, \text{{mg}}}} = 0.5 \, \text{{tablet}}
\]

### Result:
You would give **0.5 tablet** for one dose.
