3) Multiplying Fractions
Reference: Ch. 1 — Fractions — Multiplying Fractions
Stem:
The provider orders 1/2 tablet of a medication twice daily. How
many tablets will the client receive in 24 hours?
Options:
A. 1/2 tablet
B. 1 tablet
, C. 1 1/2 tablets

C: 1 1/2 tablets is too high for two half-tablet doses.
D: 2 tablets would be the result if each dose were 1 tablet.
Teaching Point: Multiply the fraction by the number of doses to
find the total daily amount.
