So, yes, the answer is false. Remember that percent is out of 100, so 40% = 40/100 = 0.40. Because we don't write unnecessary zeroes, we say 40% = 0.4, so your expression is 0.4n.
The way my algebra teacher taught me was that the percent sign was like the eyes of an angry monster which you wanted to run away from, or you could run to it if it wasn't there, by two decimal points.
65%...Oh no, run away! 65% = 0.65
56...Hey, he's not there. Let's go! 56 = 5600%
0.05%...Run! 0.05% = 0.0005
2.7...It's safe! 2.7 = 270%
And so on, and so on...
