Which expression is undefined?

D

Step-by-step explanation:

If the denominator ( bottom number ) is 0 then the expression is undefined. This is simply because a number cannot be divided by 0. However 0 can be divided by a number, the quotient would just end up being 0 though. This means that the numerator ( top number ) can be 0 and the expression will be defined

A. 0 / 3 = 0

0 is a defined answer so A cannot be the answer

B.

2 is a defined number so B cannot be the answer.

C

0 is a defined number so C cannot be the answer

D undefined

Because 15 is being divided by 0 and no number can truly be divided by 0 the quotient is undefined therefore D is the answer

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
