20 because if 9 is 45% than 1 person is equal to 5%. and if you added one more person to make 10 it would be half which is 50%. so 10+10=20 which = 100%
17.09 has 2 decimal places, so we put the decimal digits of 17.09, 09, over 1 followed by the number of zeroes equal to the number of decimal places, 2: 09 = 09/100. We add 17 as 1700/100 and get: 17.09 as decimal fraction = 1709/100
