the value of the 3 in 191.63 is 3/100th's (said as three one-hundredths, or 3 over 100, depending on where you are from usually). it is 3/100th's because it is in the hundredths decimal spot: (integer).(tenths)(onehundredths)(onethousandths) an easy way to remember the spots is to picture a 1 (one) in ur head and remembering how many zeros (or place-holders, which is just a number) it would take to get to that spot. for tenths spot, there is one zero needed, and so the picture in ur head should be 10, and thus tenths spot :) for hundredths position, there is two zeros (or placeholders) to get there, and so the mental picture becomes 100, and thus one-hundredths spot. fyi, hundredths is interchangeable with one-hundredths (meaning they mean the same thing, just different way of saying it).
144 hundredths is 1.44 so it has four each of tenths and hundredths.

0.9 is nine tenths, showed as (9/10). Just take how many places the number is, as here it is the tenths place, so its nine tenths. Example: If you want something like .75 into a fraction, seventy-five is in the hundredths place, so it is (75/100), reduced is (3/4)
It takes 200 of them.

26 of them because 26/10 = 2.6
