What's is the unit ratio of platelets to whit blood cells in a microliter of blood?

33.3

Explanation:

Normally there are 4000 to 11000 WBCs in a microliter of blood averaging almost 7500. While there are 150,000 to 350,000 platelets in a microliter blood of a normal person averaging almost 250,000. Thus the ratio can be as 250,000 : 7500 resulting in 33.3. If a range is to be given, it ranges from 31.8 to 37.5 per microliter of blood.
