Step-by-step explanation:

Total number between 1 to 100 = 100

To find, the percentage of doublets between 1 to 100 = ?

The doublets between 1 to 100 are:

11, 22, 33, 44, 55, 66, 77, 88 and 99

The total number of doublets between 1 to 100 = 9

∴ The required percentage = $\frac{9}{100} \times 100$ = 9%

Hence, the percentage of doublets between 1 to 100 is 9 percent(%).
