Answer: c ; d ; a
step by step explanation:
3/5 can be 60%. Why? If you multiply 20 with 5 and 3, it would be 60/100. It is basically the same thing as 69%.
0.60 is the same as 60% because if you made it into a fraction, it would become 60/100. In result, 60%.
6/10 is the same as 60% because if you multiplied both numbers by 10, it would be 60/100. And again, it would become 60%.
