Question

Which expression is undefined?
a. O : 4
b. 4 : 0
C. -15 = 2
d. 15 = (-2)

Answer 1

B. 4 : 0

Explanation:

4 ÷ 0 = undefined.

Anything divided by zero will always be undefined because 0 has no value and nothing times it will get anything more than 0.

Ex...

0 x 1 = 0

0 x 2 = 0

And so on..
