1. There was a sale an Bunnings. Tom got a picnic table for ⅘ of the price. (He paid $364) He also paid only 2/3 for a set of 2 chairs which saved him $39. His best bargain though was getting 60% off a big table umbrella. The original price was $580. How much money did he spend? How much money did he save?
Answer; I worked it out like this. I did 4 times what? equals 364. I first did 4 times 90 which equals 360 and so 4 was left… Then I did 4 times 1 which equals 4, so now I add 90 to 1 which makes 91 so 91 is one fifth so thats what he saved. He paid ⅔ for the chairs. He saves $39 So the $39 equals ⅓ so ⅔ equals 39 plus 39 equals $78. I had to find 60% of $580 I knew 50% was half of 580 that equals 290. So then I had to find 10% of 580 was so I did 580 divided by 10 equals 58. So he saved 232 and spent 348.

6. Sam is wallpapering his house. He has just wallpapered his lounge and this used up 9 rolls or ¾ of the number of rolls he has. How many rolls does he have altogether?
The hallway then takes a further ⅓ of what he had left. How many rolls will he have left for the kitchen? Do you think he will have enough. Explain your answer.
Answer; He used 9 rolls for the lounge which was ¾ because I put 3 in each quater and all together he had 12 rolls. Then he used ⅓ for the entrance because that was how many that was left and there was 1 in each third, so there was half left. So that meant he had 2 rolls left. I think that it won’t be enough for the kitchen because the kitchen is too big and there’s only 2 rolls.
