Answer:
3.7018867924 × 
Step-by-step explanation:
First you want to find what these two numbers are, then you divide, then you put that answer in scientific notation.
1.728(109) = 188.352
4.8(106) = 508.80
Now we divide :
188.352 ÷ 508.80 = 0.37018867924
That's a crazy decimal, but luckily because of scientific notation we can make it look a lot simpler.
0.37018867924 = 3.7018867924 × 
This should be right. Please comment if you are confused and want more detail.
