Пошаговое объяснение:

17/20 = 17:20•100 = 0.85•100 = 85%

11/25 = 11:25•100 = 0.44•100 = 44%

21/50 = 21:50•100 = 0.42•100 = 42%

0,05 = 0,05•100 = 5%

0,74 = 0,74•100 = 74%

1 1/2 = 3/2 = 3:2•100 = 1,5•100 = 150%

1 3/5 = 8/5 = 8:5•100 = 1,6•100 = 160%

2 3/25 = 53/25 = 53:35•100 = 2,12•100 = 212%
