Answer 1

The cost of 6 2/3 m of iron wire is 16 2/3 rupees. The cost of 1m iron wire is 2.5 rupees.

* 6 2/3 m iron wire is equal to 20/3 m and 16 2/3 rupees is equal to 50/3 rupees.

* So, cost of 1m iron wire = (50/3) ÷ (20/3) rupees.

* (50/3) ÷ (20/3) = 5/2 rupees. = 2.5 rupees.

So, cost of 1 m iron wire is 2.5 rupees.
