Question

Which of the numbers below correctly describes 4.7 h?

Select one:
a. 4,700 mh
b. 4,700,000 ph
c. 0.47 kh
d. 4,700

Answer 1

Answer: a. 4,700 mh

Explanation:

Assuming:

`1 mh = 10^(-3) h`

`1 kh = 10^(3) h`

`1 ph = 10^(-12) h`

The only option that is correct is a. 4,700 mh, let's prove it with the following conversion:

`4.7 h (1 mh)/(10^(-3) h) = 4,700 mh`
