1st one is 8 fifths because, one fifth is the same as 1/5 which is the same as 0.20 as a decimal. So if you divide 1.6 by 0.20 it equals 8. 2nd one is 11 thirds, so If Each 1 (as in whole) in the 3 were divided into thirds, there would be three thirds x 3 = 9 thirds, = the two thirds, is 11 thirds.
