Answer:
The answer is 100 Male chimps and 80 Female Chimps
Step-by-step explanation:
For ratio questions, you have to add all the numbers present, in this case 5 + 4 = 9. Then use 9 to divide 180 which will give you 20. To find male chimps, you multiply it by 5 and to find female, you multiply it by 4.
