A mathematical qns for the general public
-
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. -

0.5 kg + 0.25 kg = 0.75 kg
0.75 kg x 4 = 3 kg
3 kg + 0.25 kg = 3.25 kg
3.25 kg x 4 = 13 kg.
Can be solved by both model method n algebra.. hmm -

thanks vigelic but at this point we don't need more workings. haha. actually i just wanted more ppl to see how some school can teach the wrong things and insist they're right.Originally posted by Vigelic:0.5 kg + 0.25 kg = 0.75 kg
0.75 kg x 4 = 3 kg
3 kg + 0.25 kg = 3.25 kg
3.25 kg x 4 = 13 kg.
