Can learn simultaneous equations indirectly one meh?PiggyLalala:
Just to clarify. If I did not remember wrongly, I did not see any worksheets that specifically taught simultaneous equations, and neither did the teacher specifically teach the skill to the pupils. However, in class, the teacher might have used it as a method to solve certain practice questions, which allowed the better students to indirectly learn the way of doing simultaneous equations.

Just a word of caution, when i said 'simultaneous equations', it does not mean the complicated 'simultaneous equations' like above.jesschan,

I think the above solution is too complicated for the P6 students to handle. -

Oh boy... this is getting out of my depth... :siam:

Do you have a simpler solution? -

How shall i put it? :? so sorry.. not very good in expressing....

Copied the question from the PSLE maths thread.
Beautiful solution provided by Mathizzzfun and tianzhu.. -

Primary school questions do not really need the skills of simultaneous equations. Such questions can always be done by other methods without using simultaneous equations.

sorry… don’t know how to link… refer to page 484… psle maths thread

Is it this one the simple solution? http://www.kiasuparents.com/kiasu/forum/viewtopic.php?p=693236#p693236
Looks very Onspongey...
By the way... Onsponge 6 addresses simultaneous equations using units or something like that. -
Just to share… my ds way of doing the above questions… Concept used = RATIO, and need a bit of simple simultaneous skills…
A: shaded: unshaded = 1u:1u
shaded: unshaded = 1p:4p
B: shaded: unshaded = 1u + 1p: 3u+3p
Given area A+B = 125% tt of C,
therefore 2u + 4u + 4p: 5p = 5z: 4z
6u + 4p = 5z ----- (1)
5p = 4z --------(2)
from (1) 24u + 16p = 20z
from (2) 25p = 20z
therefore 24u + 16p = 25u
24u = 9p
8u = 3p
4u = 3/2p; 2u = 3/4p
Therefore area A/area B = 2u/4u+4p = 3/4p divide by (3/2p +4p) =3/22.
