Answer 1

12 × 1/3 hour

Explanation:

1/12 tank in 1/3 hour.

1/12 is one-twelfth of the tank.

there are 12 twelfths in an unit. The tank has 12 one-twelfth parts, so you need to fill 12 times 1/12 of the tank.

Since it takes 1/3 hour to fill 1/12 of the tank, it will take 12 × 1/3 ghour tio fill the entire tank.

The expression is

12 × 1/3 hour
