Dividing by 10

Work out saving per item by dividing by 10

The first question in this topic is as follows. If marbles cost 10 cents each, but a packet of 10 costs 90 cents, what is the amount you save PER ITEM by buying the packet.

So, if a packet of 10 marbles costs 90 cents then each marble in the packet costs:

90 ¢ ÷ 10 = 9 ¢ per marble

Which compares to 10 ¢ if we buy them individually.
So in this case the saving PER ITEM is:

10 ¢ - 9 ¢ = 1 ¢ per item

If you are finding this difficult, you might like to work through the lesson Introduction and Either / or activities before tackling the games.
