12/49

4*3=12
7*7=49
12/49 miles long is being repaved.

This can be tested by taking a mile (in feet for example) and multiplying 5280 ft by 4/7 then by 3/7 to get the same answer as taking 5280 ft times 12/49.

Disadvantage :- Such circuits can draw more power which leads to high bill charges on electricity. Also such connections need more wiring.
