The given decimal fractions are 0.65, 2.1, 0.02, and 12.35.

Therefore, we have,
0.65= 65 100 Percentage = 65 100 ×100 =65%   2.1= 21 10 Percentage= 21 10 ×100 =210%   0.02= 2 100 Percentage= 2 100 ×100 =2%   12.35= 1235 100 Percentage = 1235 100 ×100 =1235%   Hence, the percentage of the decimal fractions 0.65, 2.1, 0.02, and 12.35 are respectively
65%, 210%, 2%, and 1235%.
