8. How many micrometers are in .025 centimers?

9. How many decigrams are in .45 grams?

10. How many milligrams are in 1.37 hectograms?

11. 12.6 deciliters are equal to how many liters?

12. 8,300 milligrams are equal to how many grams?

13. How many decimeters are in 4.7 meters?

15. If you have been alive for 504,576,000 seconds, how old are you (years)?

I have my answers but don't feel like typing them. Can someone answer all these so I can match them up. Thx (:

No.

Honestly, I don't believe you.

I will do two as examples of the unit conversion process.

12. 12.5 deciliters( 1 liter/10 deciliters)=125 liters (notice the deciliters divide out).

15. 504,576,000seconds(1hr/3600sec)(1day/24hr)(1year/365days)=
504,576,000/(360*24*365) years

1 is done this way.
6.5 hr/day for 5 day = 32.5 hrs

There are 60 minutes in an hour
There are 60 seconds in a minute.
Put all of that together in the form of dimensional analysis to obtain
32.5 hr x (60 min/hr) x (60 s/min) = 117000 s.
