Hi lulu2014

Good Afternoon.

Here’s an example for a similar question. Please refer to the slide.

When students are able to understand the logic behind the solution, MD might not be necessary.

Another question for your kid to practise.

Miss Lim bought a packet of sweets to distribute to her class. If each child gets 3 sweets, she would be left with 30 sweets. If each child gets 4 sweets, she would need 5 more sweets.
a) How many children are there in the class
b) How many sweets did Miss Lim have at first.

The solution to your question, in order to send the same companies 1 more ticket (4 -3), Mr Tan needs 70 (50+20) charity tickets.

Number of companies ------ 70/1 ------ 70

Number of tickets ----- (70*3) + 50 ----- 260

Best wishes

Hope this helps.

Best wishes

1/4 of C --> 1/3 of J (make numerator the same but it is already the same to begin with]
so, C has 4u and J has 3u to begin with.

Charles: June
= 4u : 3u
-150 : +80
----------------
2p : 5p

Making the parts the same, meaning x5 for Charles and x2 for June,
20u = 6u + 160 + 750
14u = 910,
1u = 65

This method can be found in Onsponge:)

i had a hard time understanding.

3) Jimmy and Kelly had some cards. In a game, Jimmy lost 1/10 of his cards to Kelly. After Jimmy lost his cards to kelly, the ratio of the number of cards Jimmy had to the number of cards bKelly had was 3:1. The next day, after Jimmy lost more cards to kelly, the ratio became 4:7 and kelly had 72 more cards than Jimmy.
a) what was the ratio of the number of cards jimmy had to the number of cards kelly had?
b) How many cards did kelly win from jimmy altogether?

5) Alex, Boon kheong and Casmuri paid for a meal. Alex paid 1/5 of the amount Boon Kheong and Casmuri paid altogether. Boon Kheong paid 1/4 the amount Alex and Casmuri paid.
a) what fraction of the total cost of the meal did Casmuri pay?

Re: Q&A - PSLE Math

The student had read the time on the left clock wrongly. It should be 2 pm not 12.10 pm.

From 2 pm to 3.15 pm the long hand moved 1 and 1/4 circles.
So altogether there are 5 right angles.
