Dear all


Apologies. Just wanted to see if there’s any possibility of using model to explain the question. Once again, really appreciate all your help.

A baker has some flour. He uses an equal amount of flour to bake cakes everyday. After 6 days, he has 3/5 of the flour left. After another 4 days,he has 15kg of flour left. How much flour did he have at first?

Just wondering how to solve this instead of using algebra method.


Mr tan has some tickets. If he sends 4 tickets each to some companies,he will need 20 more tickets.
However, if he sends 3 tickets each to the same companies, he will have a remainder of 50 tickets. How many tickets did he have?

Thanks!!

Thanks once again.


May I know how did u derive 15 units?

For the second question, I was able to solve with model but when I used the branching method, I could not. Would u be able to do it via that method?

Thanks!!

4/4 -- 1/4 shoes
-- 3/4 remainder -- 1/6
-- 5/6 5/6x3/4= 15/24

15u --> 125?

Thanks Bluebelt for your detailed explanation

Thanks so much.


Was trying this:
Pam’s savings was 3/7 of Mary’s savings.
Jan’s savings was 2/5 of the total savings of the three children.
Pam and Mary have $240 more than jan.
How much is pam’s savings?

P:S —> 3:7
J: P+ S—> 2:4

Is this right? And how do I do the next step?

Thanks !!

Thanks


Just to check how did you derive 35u:45u ?

Appreciate your help.
