Answer:
80%
Step-by-step explanation:
So you basically, just make it a ratio. Since a percentage is out of 100, just make the 5 into 100. To get 5 to 100, you times 20. Then you do the same thing to the 4 which you get 80.
That is a ratio. If you mean the simplified version, then 2:7
Move over 2 decimal places
This would be 38.4%
