If a paper clip becomes a temporary magnet, one end of the paper clip will have a negative charge, and the other end will have?

The strong magnet aligns the magnetic domains within the paper clip. In an ordinary iron paper clip the magnetic domains are present, but they are random, pointing in different directions. This cancels out their potential magnetism. When introduced to a strong magnet, the domains become aligned and begin to point in the same direction. This, in turn, makes the paper clip magnetic.

Hope This Helps i hope i didn't do anything wrong

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
