1. If a times 4 / 5 = B divided by 4 / 5 = C, and ABC is greater than 0, then () > () > 2. It is known that a multiplied by 1 / 2 = B multiplied by 0.05 = C divided by 1 and 1 / 3, where the largest number is ()
4a/5=5b/4=c
So a = 5C / 4 > C
b=4c/5c>b
A/2=B/20=3C/4
So a = 3C / 2 > C
A=B/10A>C
So B is the biggest
