Answer:

Step-by-step explanation:
1. Density

2. Specific gravity
Specific gravity (sp gr) is the ratio of the density of the density of a gas to the density of dry air at standard temperature and pressure.
At IUPAC standard temperature and pressure (0 °C and 100 kPa), dry air has a density of 0.080 lb/ft³.

5+4/6
Result: 17/3
OR
5+1/2+1/6
5+4/6=17/3
Hope this helps!
