990 or 10<1000?
9 is less than 10.
1000 times less
Less than 10
1944 M = 1000 CM = 900 (100 less than 1000) XL = 40 (10 less than 50) IV = 4 (1 less than 5)
10 less than 5
M = 1000, CM (100 less than 1000) = 900, XC (10 less than 100) = 90 and IX (1 less than 10) = 9. So the complete numeral MCMXCIX represents 1999.
Any number of years greater than 10 but less than a 1000 such as a century which is 100 years.
472 is 10 less than 482.
9999
The number that 30 is ten less than is 40. Half that is 20. So the question becomes "what number is as much more than 10 is less than 20". This is gobbledygook, but if I rephrase to say "what number is as much more than 10 than 10 is less than 20", then since10 is less than 20 by 10, I guess 20.
