Answer:

1. 125 cm and 275 cm

Step-by-step explanation:

1. 400 cm in total

  Subtract 150 for the longer stick and you are left with 250 cm.

  Divide 250 cm by 2 because you have two sticks, and you get 125.

  That's how long the shorter stick will be.

  For the longer stick, take the other 125 cm left and add the 150 cm that you subtracted earlier because that's how much longer it is than the shorter stick.

  So... 125 cm for the shorter stick, and 275 cm for the longer one
