Dividing by 8
Work out the saving per item by dividing by 8
This topic focuses on the idea that you can often spend less per item if you buy a packet or so called mutli-pack. Manufacturers often accept less per item when selling more of a particular item. So, how can we work out how much is saved per item if we buy in bulk? What we need to do is work out the cost of each item in a pack, and compare that to the cost of an item bought singly.
The first question in this topic is as follows. If marbles cost 8 cents each, but a packet of 8 costs 56 cents, what is the amount you save PER ITEM by buying the packet.
So, if a packet of 8 marbles costs 56 cents then each marble in the packet costs:
56 ¢ ÷ 8 = 7 ¢ per marble
Which compares to 8 ¢ if we buy them individually.
So in this case the saving PER ITEM is:
8 ¢ - 7 ¢ = 1 ¢ per item
Note that you could also approach this problem through multiplication. Rather than dividing the packet price by 8, you could multiply the cost of the single item by 8. This would give you the difference in price for a packet. You would then need to divide to get the saving 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.
With our Four in a row math game you will be practicing the topic "Dividing by 8" from 4th grade / Multiply + Divide / Best Price. The math in this game consists of 16 questions that ask you to use division by 8 to work out the best value for money item.
Word problems: best price per item
Learn how to work out saving per item by buying a packet or box rather than individual items
In these math topics, we explore division by working out what the price per item is if you buy a whole pack or other group container like a box or a book (of stamps). Often retailers will price a group of items in a box or packet at less per item in order to sell a greater quantity of items.
For instance, buying individual marbles might cost 10 ¢ each, but buying a packet of 10 marbles might cost say 80 ¢. In this case, you can probably see immediately that the pack price is "better" than the individual price, but how can we work out what the acutal saving is? There are 2 simple ways to work out the saving: either multiplying the individual item price by the number of items sold in the packet, or dividing the packet price by the number of items in the packet. If we do the latter we find that the price of each marble in the packet is
80 ¢ ÷ 10 = 8 ¢
Which compares to 10 ¢ if we buy the marbles individually. So in this case the saving ** per item ** (which is what these topics are about) is:
10 ¢ - 8 ¢ = 2 ¢
Next time you are in a shop where you can choose to buy a packet or individual items, see if you can figure out what the saving is... it could save you a packet!
The game will reinforce the math you have chosen to learn by getting you to match the question to the correct answer.
