Thank you Adrian

I will.... But can you repost the question in the correct orientation?

4 units actually equals 252 + 300 =552 1 unit =138 Thus Sufia left 138

4 units = 552

Thanks everyone!

200% is not 1/5

200% is actually 2 times (200/100, omit all the 0, hence you will get 2), meaning Elle has 2 times as many muffins as Francis. Hope the answer is correct and the working helps you !

May I know how to explain to kid 9u - 18 = 3x ~ x4 10u - 14 = 4x ~ x3 TQ

Make equations based on the model drawings. Thus, Diana 9◻️ - 18 muffins = 3x Francis 10◻️ - 14 muffins = 4x

Since the question wants Elle, meaning we want 20 ◻️, hence you have to get rid of X. If your child doesn't understand what is u, you can use ◻️ instead..

Ok thanks...trying to digest. :)

Is this answer correct?

Is the answer $840?

The correct answer is $840 but solving it requires student to work with 'parts' and 'units' which is not expected of students at this level nor PSLE.

Hmm… please show working, thanks

Let y be the total. Y/8 +175 + 455 + shoes = y Y/8 + 175 +455 + 3/11(y - 455) =y Y=840

Units and parts IS in the PSLE syllabus... Can a model method solve this problem?

Yes a model can help. This question touches on fractions too

Eunice Leong..tried using model but is difficult to cut bcoz 455 is not divisible by 11... Can only think of algebraic method...but need to explain to my kid... Care if someone can draw the model...

Thanks Rye Tan....its quite complicated with the fractions.. wondering whether a PSLE student can comprehend this..hopefully this QN will not be in this year PSLE.... Once again..thank you

It's really complicated. I couldn't figure it out. Thanks for the effort and answer.

Do you need any help in the explanation?

Yes, Ryan Tan, thanks.

From the model I gather that 1 unit=$35....total 24units 13units--$455 3units-shoes 8units-$175+ 1/8 of 24 units 8units= $175+3 units 5units=$175 1 unit=$35.. That is what I see from the model...is it really necessary for those fractions with 'weird' denominators..LOL

Izam how did you get 24 units in the first place? G&C?

Sorry I was calculating 8/8 minus 175- 1/8 as 7/8-$175 which is wrong!! Got a negative value for the shoes...so I should agree that the fractions like 175/8 is necessary for this.. Thanks once again

Okay, I got it. Thanks

Chek HG Moon - my P5 girl used a slightly different way to solve this question. Since they have the same denominator, she omitted them (eg 7/8 became 7u and 8/8 became 8u). No need to do complicated decimals. Hope it's correct to do it this way !

Pauline Vong Nyit Li...after going thru what we had gone thru yesterday your working is showing 3 units for shoes which is not possible unless its an assumption... Decimals is definitely required for these question... How do you get the shoes to be rightly 3 units in the first place?

IMO, this problem has errors everywhere. If I remember correctly, even when the final answer is $840, the price of the shoes does not end in 2 d.p.

Izam Marwasi it is a fact not an assumption. Question says 3/11 of the remaining money on shoes, hence 3◻️ is for shoes and 8◻️ is for watch ($175) + left with 1/8.

No ...I don't think so...your working does not show that...

Pauline's solution is correct. It is the standard solution for "units and parts".

OK..thanks ...sorry Pauline Vong Nyit Li..

No worries.. Izam Marwasi.
