[quote]Mrs Lim bought 7/8kg of flour. She used 4/7kg of it to bake a cake and 3/8kg to make muffin. How much flour Mrs Lim is left with??

Hi, I have seen a similar question before, is simply just 7/8 - 4/7 - 3/8, but we can't minus, not sure if there is a error in the question.[/quote]
HI! :oops: Sorry, yes , there is an errror in the earlier question,,,,, should be:

Mrs Lim bought 7/8 kg of flour.
She used 4/7 of the flour to bake a cake and 3/10 kg to bake some muffins.
How much flour did she have left?

Hi, I need help in solving this question by using bar drawing method.

4 packets of biscuits and 3 packets of chips = $13.10
6 packets of biscuits and 12 packets of chips = $35.40
a) what is the price for a packet of chip?

Thanks in advance
Hmm... I won't use models for such questions.... can use symbols or tables

By using symbols.... (Please note that there are many variations to this mtd... easier to get rid of B first)

4B 3C -> $13.10
6B 12C -> $35.40
12B 9C -> $39.30
12B 24C -> $70.80
15C -> $31.50
1C -> $2.10 (Ans)

or

4B 3C ->$13.10
6B 12C -> $35.40
16B 12C -> $52.40
10B -> $17
1B -> $1.70
4B -> $6.80
3C -> $13.10 - $6.80 = $6.30
1C -> $2.10 (Ans)

By using table...

I need the solution for this question....


Mrs Lim bought 7/8kg of flour. She used 4/7kg of it to bake a cake and 3/8kg to make muffin. How much flour Mrs Lim is left with??

Anything near will help.
There should be a mistake in the qn in the 2nd line:
She used 4/7 of it i.e. 4/7*7/8=4/8=1/2kg to bake a cake and 3/8kg to make muffin
So total used = 4/8+3/8=7/8kg.
Ans: All flour used up, so no flour left.

Or She used 4/7kg (no such thing as 4/7kg of it) That's why can't do 7/8-4/7-3/8 (will get negative ans)
HTHs 🙂

It is really very kind of you to offer your service. There are so many wonderful people in KPS.com. I have a suggestion, before things get out-of-hand, and for more parents to benefit, please have the Q&A a little more organised.

Chief Kiasu, if you are reading, can u organise it so it is easier to read and follw up? A little more structure will help a lot! 😉

Q1

Ravi and Timothy have a total of 468 Stamps. They have the same number of stamps. How may stamps must Timothy give to Ravi so that Ravi can have 50 more stamps than Timothy?

Another way to look at this problem.

The total number of stamps remains the same.

In the beginning, Ravi and Timothy have 234 stamps each.(468/2)

At the end,Ravi has 259 stamps and Timothy has 209 stamps
(2 units + 50 --> 468) ---You may wish to draw a model.

Therefore, Timothy must give 25 stamps to Ravi. (234 - 209 -->25)
Thanks Tianzhu for your kind advise. It really helps....

You may post the questions here/PM me or email me and I will try my best to solve it at soonest and post the question/answer here so other parents who have doubts on the same type of questions may help their kids too
TIA for helping to solve these P6 questions.

Q1
The distance between A and B is 7 km. At the beginning, both Gregory and Catherine are at A. Gregory walked from A to B at a constant speed. After Gregory had walked for 1 km, Catherine discovered that he had left his belongings at A. She immediately ran after him at a constant speed of 4 km/h. After handing over the belongings to Gregory, she turned back and started running towards A at the same speed. Given that both Catherine and Gregory reached A and B respectively at the same time, what was Gregory’s speed?

Q2
Paul and James went out for a cycle and were 16 km from home when Paul ran into a tree damaging his bicycle beyond repair. They decide to return home and that Paul will start on foot and James will start on his bicycle. After some time, James will leave his bicycle beside the road and continue on foot, so that when Paul reaches the bicycle he can mount it and cycle the rest of the distance. Paul walks at 4 km per hour and cycles at 10 km per hour, while James walks at 5 km per hour and cycles at 12 km per hour. For what length of time should James ride the bicycle, if they are both to arrive home at the same time?
