THought i created this topic here because some people from the
Homework forum were inept. Not that i can't solve this qns but
someone else obviously don't believe my workings, so i thought i
had to prove to them.
This is a primary six qns though. 
Mrs Lee bought a packet of rice from the grocery shop. she used 3/4
of the rice and another 1/4KG of the rick to cook lunch. Then she
used 3/4 of the remaining rice to cook dinner and another 1/2KG of
rice to make shushi rolls. Finally, se used the remaining 1/4KG of
the rice to make rick cakes. How much rice did mrs lee buy from the
grockery shop?
*note the difference with the fractions and fractions of
weights.
