Answer:
6
Step-by-step explanation:
If 60% are yellow, the other 40% are green. Then the difference between yellow and green is 60% -40% = 20% of the total number of fish. That difference also happens to be half of the number of green fish:
20% = (1/2)(40%)
So, the number of green fish is 2×3 = 6.

If you wanted to, you could write a couple of equations:
y - g = 3
y = 0.60(y +g)
Using the first equation to write an expression for y, we get ...
y = g +3
Using this in the second equation, we have ...
g +3 = 0.6(g +3 +g)
g +3 = 1.2g +1.8 . . . . eliminate parentheses
1.2 = 0.2g . . . . . . . . subtract g+1.8
1.2/0.2 = g = 6 . . . . . divide by 0.2
There are 6 green fish in the aquarium.

Step-by-step explanation:
3 and 5 are prime but there is no commeon factor among the three numbers so you directly multiply 3 4 and 5.
The ratio for the cups of orange juice for every cup of fruit punch is 3:4.
Since now the cups of orange juice ratio has been altered, the cups of fruit punch ratio needs to be equally altered as well.
12/3 = 4
4(4) = 16
Now that they are equally altered, the new ratio would be 12:16
