Answers:

0.85 = 85/100 - because of the two numbers on the right hand side. Then (divide by 5) 85/5, 100/5 = 17/20

2116/100 - divide by 4 for 2116/100. 2116/4, 100/4 = 529/25

22.15 = 22 15/100 = 22 divide by 5 for 15/100. 22 3/20. Multiplied 22*20=440

Then add 440 with the numerator. 440+3=433/20
