Christmaths Advent Calendar 2013: Day 1

This year’s Christmaths Advent Calendar will have a question for every day in December up to and including Christmas Day, each one featuring a new mathematical challenge.

A length of tape is 135 centimetres long.

It is cut into two pieces.

The first piece is twice as long as the second piece.

How long is the shorter of the two pieces of tape?

      You are both correct. The remaining piece would be 90cm long.
