 P: 21 if 1 century = 100, and 100 centuries = 10,000, does 154 hundred thousand centuries = 154,000,000? So it's same as 154million years? Or is it 154 * 100,000 = 15,400,000 * 100 = 1,540,000,000? 1.54Billion? or is it 15,400,000? thank you.

 Quote by Gomar 154 hundred thousand centuries
This is a really awkward word construction that no one would ever use, but if I heard it, I would interpret it as meaning 154 * 100,000.
 P: 13 1 century : 100 years 100 : 10000 years 15400000 : 1,540,000,000 is it?

Sorry I just realized this was ambiguous. I would interpret it as meaning:

154*100,000 centuries = 15,400,000 centuries

= 154*100,000*100 years = 1,540,000,000 years

i also confused with your earlier post..
 P: 750 century = 100 154,000 * century = 154,000 * 100

 Quote by Number Nine century = 100 154,000 * century = 154,000 * 100
1 century = 100 years
154,000 * 1 century = 154,000 * 100 years
 P: 21 I am confused. Is the correct answer: 1,540,000,000 years or not?

You have the answer. What's 154,000 * 100?

 Quote by Number Nine You have the answer. What's 154,000 * 100?
So it's 15,400,000
not
1,540,000,000?

 Quote by Gomar does 154 hundred thousand centuries = 154,000,000? thank you.
prof says 1,540,000,000 is right. as you have to multiply 10,000,000 by 154.

 Quote by Gomar So it's 15,400,000 not 1,540,000,000?
These are BOTH right. The first one is the answer in units of centuries, and the second one is the answer in units of years. At least two people have already explained that. I'm not sure why you're making this so complicated.

Especially with such a weirdly worded question - "what is 154 hundred thousand centuries?"
