If Sara can only work 5% of one hour now many minutes of one hour can Sara work?

5% or 5percent can be thought of 5 per 100.

5 per 100 or 5 out of 100 can be written as 5/100 or 1/20.

An hour have 60 minutes and 1/20 of an hour is 60*1/20=3 minutes.

Therefore Sara can work 3 minutes every hour.

1. minimum

2. 6400

3. eight

hope this !
