Pls help me with my son's H/W...


Minghua gave 1/2 of his money to Lily,.
In return, Lily gave 1/3 of whatever money
she had to Minghua.
Later, Minghua gave 1/4 of whatever
money he had then to Lily.
Finally, Minghua had $675 and Lily had $1325.
how much money di Minghua have at first?

From the question, the total amount of money they had = 1325+675 = $2000\t

At final stage:\t
Minghua
3/4 Unit = 675
1/4 Unit = 225
1 whole = 900
so before that Minghua had $900 nad Lily had $1100\t
\t
Lily
2/3 Unit = 1100
1/3 Unit = 550
1 whole = 1650
so before this Lily had $1650 and Minghua had $350\t

Minghua
1/2 Unit = 350
1 whole = 700

Minghua had $700 at first.

Hi Tianzhu! Haven’t seen you around in a looooong time. How’s it going, buddy?

Hi, young man muffins


May you have a wonderful time in your secondary school. Enjoy your studies and CCA.

Good cheers, Good health and a Happy New Year.

I’ve not been posting solutions actively because I am getting rusty as I’ve not been reading up much since PSLE. Also, kiasu PSLE 2010 kids are very fortunate to have a professional tutor like mathsguru who is pretty keen in offering her expertise in the self help threads.

Best wishes
