Question

4. If 104 um = 1 cm, how many um = 1 cm'?
(A) 104
(B) 106
(C) 108
(D) 1012​

Answer 1

I would assume the answer is (A) 104.

Explanation:

This is because in the question, you already stated that 104 um = 1 cm, so naturally when asking the question how many = 1 cm, then I would think the answer is 104.

Hope this helped!
