Cham lah my dd went to write the MT compo abt stealing :yikes: cos he say the pic was not obvious is taking wrong bag by mistake :stupid: i think his compo fail liao becos totally out of point :gloomy:

It will depend on how he describe the incident.

For example, if the bag looked exactly like mine, I might try to steal it. If I were caught, I could then denied that I had mistaken it to be mine.

]Su ying baked some pies.She gave 1/5 of them to her relatives .Then she gave 30 of them to her neighbours .She then had 2/3 of the pies left.She then packed the rest of the pies into 18 boxes.Each box has either 6 or 12 pies.

(a)How many pies did she pack into the 18 boxes?
(b)How many boxes had 6 pies ?

My DD put for (a) 150 and (b) 11.Is she right?[/quote]

Based on information you provided, the answers did work out to be 150 and 11. :boogie:[/quote]

Thank you for the prompt reply:) hope the info given by her is correct ;([/quote]

I am sure someone will reaffirm this in no time. :xedfingers:

Based on info provided, the answers are correct.

1/5 = 3/15

2/3 = 10/15

15 - 3 - 10 = 2 u --> 30

1 u --> 30/2 = 15

10 u --> 15 x 10 = 150 (ans a)

18 x 12 = 216

216 - 150 = 66

12 - 6 = 6

66/6 = 11 (ans b)

there was one question in paper 1 where they had to draw a rectangle twice the area of the trapezium.. my dd said that they did not learn how to find the area of a trapezium? :yikes:

Area is Average of 2 lengths x Height

The trapezium can be broken down into a rectangle + 2 triangles.
