c. 146%! :D
I learned this in one of my classes a few months ago, so I don't know if this is how to explain the way of making a decimal, but here goes;
To get the percentage, multiply the decimal by 100. It is that simple really, but I forgot if that is the way to convert decimals for all decimals like (EX) .67 or 1.5! But I hope this helps and you get it right! Let me know though oki doki?
