1:3 can be another ratio of black fish to white fish
0.345 or .345
Step-by-step explanation:
because that is the highest decimal number because it has higher values, I mean "345" is greater than "33", "35", and "332".
the only way the smallest number would be the highest number is when it have a negative symbol to it e.g -0.1 is greater than -0.2 due to the fact that -0.1 is closer to 0,1,2,3,..... than -0.2 According to the number line.
All I'm trying to say is that, if it's not a negative number then the one with the highest value or number is actually the highest number EXCEPT if it Hans the negative symbol (-) to it, then it's the opposite meaning the "smallest number" would be the highest number.
Hope this helps buddy, Good luck ✅.
