we have to add three decimals that have a sum of 27.905
parts that are given is 14. + 8. + 4.
if we add these we get the sum of 26, so we need 1.905 more, if we add 0.95 + 0.5 + 0.5 we get 1.905
So, if the numbers are 14.905, 8.50 + 4.50 and we add these numbers we get the answer 27.905
14.905 + 8.50 + 4.50 = 27.905
Thus, the three decimals that have sum of 27.905 are 14.905, 8.50 and 4.50.
