Suppose that 19 inches of wire costs 57 cents. at the same, rate how many inches of wire can be brought for 36 cents?

  12 inches

Step-by-step explanation:

Since you know your multiplication tables, you know that 57 = 3·19, so the wire is 3 cents for each inch. Then you also know that 36 = 3·12, so 12 inches of wire will cost 36 cents.

___

You can also write the proportion ...

  19 in/(57 cents) = x/(36 cents)

Multiplying by 36 gives

  x = (19 in)·36/57 = 12 in
