8    1/2      by      11.

Area1  =    8    1/2  ×  11

Area1 =    17 / 2  × 11 = 187/2


17/10      by     2  1/5

Area2  =    17/10  ×   11/5

Area2 =    17 / 10  × 11/5 = 187/50


Scale factor =  Area1 / Area2

                     =    187/2    ÷ 187/50

                     =    187/2  ×  50/187

                     = 25

Scale factor = 25
