Explanation:

If one price is 2 times the other one, that means it's equal to 2 of those parts. Let's decide our total wire by three to account for the larger part.


90 / 3 = 30

Now we know the shorter piece is 30 cm. To find the longer piece, multiply the shorter piece by 2.


30 * 2 = 60

Recap:

Shorter Piece: 30 cm

Longer Piece: 60 cm

That's all there is to it! hope this helps.
