Question

Can someone plz explain this to me that's all I need is an explanation to this question not the answer. Thank you!
Question:An oil company fills 1 over 12 of a tank in 1 over 3 hour. At this rate, which expression can be used to determine how long will it take for the tank to fill completely?
Answers:
1 over 12 ⋅ 3 hours

1 over 3 ⋅ 12 hours

1 over 3 ⋅ 1 over

12 hour 3 ⋅ 12 hours

Answer 1

\(\large \frac{1}{12}\) of tank ------------------> \(\large \frac{1}{3}\) hours

multiply by 12 on both sides

\(12 \large \times \frac{1}{12}\) of tank ------------------> \(12 \times \large \frac{1}{3}\) hours

\(1 tank ------------------> \(4\) hours

Answer 2
