Is it really a bargain? Sometimes shops try to trick us into thinking that items are a bargain when they may not be. For example, do they think we might not buy a $9.99 book if the price sticker said $10? There hardly seems to be a day that goes by without shops offering items at discount prices. The discounts are often shown as a percentage.

For math this week, we were studying about percentages discounts. From what I understand so far, we can find less-common percentages of an amount (such as 11%) by converting to decimals. To explain the method, let’s start by finding 1/4 of $10. (we already know that 25% of $10 is $2.50, so we’ll know if the method works.)
1/4 = 25/100 = 0.25
0.25 of $10 is the same as 0.23 x 10.
0.25 x 10 = 2.5
So, 25% of $10 = $2.50
How simple is that?

Right now, we’re working on a new unit and topic which is about patterns. I’ve caught up with the work, but the rest of my classmates didn’t so I’ll update you when Whaea introduces the topic to everyone. I’m two steps ahead.
Thanks for reading!
