Answer 2

Answer:

The cost of 1 litres of milk is 19 15/18.

Step-by-step explanation:

Cost of 4 1/2 = 9/2 litres of milk = 89 1/4 = 357/4

Cost of 1 litre of milk = 357/4 ÷ 9/2

                                 =) 357/4 × 2/9

                                 =) 357/18

                                 =) 19 15/18

Therefore, the cost of 1 litres of milk is 19 15/18.
