Meg and Mo still need to hang their marbles so that they balance,
but this time the constraints are different. Use the interactivity
to experiment and find out what they need to do.
Mo has left, but Meg is still experimenting. Use the interactivity
to help you find out how she can alter her pouch of marbles and
still keep the two pouches balanced.
Congratulations to Debbie and Fiona, Catriona and Ellie from The Mount School in York who completed full solutions to this problem:
Emma, also from The Mount School, offered the following explanation of how to work on these problems:
Meg: 10 x 30 = 300
When you multiply the number of marbles in the bag by the distance from
the pivot point you get the same answer on both sides.
* 90cm = 900
* 150cm = 900
