1 is incorrect. If you were to figure this on your calculator, it would be 1 / 5 = 0.2, or 20%. Percentages are the quotients (the answer of a division problem) with the decimal moved two spots to the right, and vice versa. This is achieved by multiplying any quotient by 100% to get its respective percentage.
#2 is incorrect. 7 divided by 10 is 0.7
#6 is incorrect. 2/5 = 0.4, so the answer is 2.4
