Answer 1

Answer:

It takes 3 hours to fill 4 oil tankers

Step-by-step explanation:

6 oil tankers = 9/2 hours

1 oil tanker = 9/2 ÷ 6

                 = 9/2 x 1/6

                 = 3/2 x 1/2

                 = 3/4

4 tankers = 3/4 x 4               (4 cancel out with 4)

                 = 3 hours
