Question

A wire 90 cm long is cut into two pieces. One

piece is twice as long as the other piece. How
long is the shorter piece of wire?

Answer 1

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.

Answer 2

30 cm

Explanation:

30+60=90

30×2=60 so 30cm is the answer.
