Thanks Bhavin

In order to compare both ratios, write down the ratios as follows and count the total units per ratio. Then find the common multiple of the total in order for comparison. (ie. Since the remaining number of jelly beans in both situations is the same) Lowest common multiple of 9 and 12 is 36. Hence, the units in first ratio x4 and the units in 2nd ratio x3. Comparing the ratios, we can see that there's a difference in 1 unit. Therefore, 1 unit represents 12 jelly beans. Number of green jelly beans at first = 21 x 12 = 252

thanks. tough for me to understand but kid understand 😊

Glad to be able to help :)

Thanks Yueh Mei

Correct me if I am wrong.

J->3u D->12u R->10u D-R->12u-10u->$40 2u->$40~~1u->$20 10u->$200 (Rick's share) Total->25u->$20x25=$500(ans,)

How u assign the u to each person? I don't understand this part.

D is 4 times J U assign any no of units to J.. eg if u assign 12u to J then D will have 48 units.. D+J->60units-> 60% of the total since R is 40% of the total. 60u->60% 40u-> 40 % In this case D-> 48u R->40u. J-> 12u D got $40 more than R.. So D(48u) minus R(40u) is equal to $40...

Another way is to assign 40u to R 40%-40u 60%->60u(D+J) D:J-> 4:1

100% is 10u, 40% is 4u. D's share is $40 more than R-- 4u+40. J is 1/4 of R-- 1u+10.

Thanks guys. U r fantastic. Now I understand.

Sorry! Make a mistake. Edited. : )

Ho Cheng Sun, you may want to use ratio to help you decide the number of units to use using the concept of lowest common multiple since dick's +jake's share is the same

my P5 girl did this, she think it is easier to understand using fractions and units.. she is my tutor for maths these days...

Rick: 40% of sum Dick: 40% of sum + $40 Jake: 10% of sum + $10 Sum = 100% 40% of sum + 40% of sum + $40 + 10% of sum + $10 = 100% of sum :)

J-> 6u....D-> 24u

Correct

Note: Dick's share was 4 times that of Jake.

Thanks Vanessa.

Welcome!

Thank you for spotting the mistake

Thanks Sock Lang. Nowadays kid is smarter than adult.

Ho Cheng Sun yes in my case...LOL

Thanks Brandon

Thanks!

Angle CAE = 90 - (11 x 4) = 90 - 44 = 46° Angle AEF (the corner which has been folded up) = 90°

Oh I see! Thanks a lot!
