It could be: 9 = IX as a Roman number and by deducting I it becomes X = 10
10-(-1)=9
19
10 1/3 + 7/9 = 11 1/9 or eleven and one ninth.
decreasing 100 by 10% (10) would equal 100-10=90 Increasing 90 by 10% (9) would equal 90+9=99
90% is equal to 0.9, so 0.9 times 10 is equal to 9. Answer: 9
Ten kilometers is equal to approximately 6.3 miles.
Expressed as a decimal, 9/10000 is equal to 0.0009.
It is: 10+(-1) = 9
9 hours and 10 minutes equal 890 minutes. there are 1440 minutes in a day. 890/1440 is about 62%, or .62.
One way to make an expression equal to 10 using five 9's is: 99 - 9 - 9 - 9 + 9 = 10.
Using Roman numerals 1 = I and 10 = X. If you put them in front of each other one then ten you get IX, which is 9 in Roman numbers.
