tq

tukarkan dulu kpd pecahan tdk wajar...
= (6 x 5 + 1 per 6) - (3 x 3 + 2 per 3)
= 31/6 - 11/3
tdk boleh selesaikan kerana pembawah tdk sama...
maka, samakan pembawah...
= 31/6 - (11/3)darabkan dgn 2
= 31/6 - (11x2)/(3x2)
= 31/6 - 22/6
= (31-22)/6
= 9/6
= 1 3/6
ringkaskan lagi...
= 1 1/2...#

atau satu lagi cara cuba begini ja:

since pembawah /denominator boleh disamakan jadi boleh asingkan no bulat dn pecahan.mudahkan dn selesai jln pndek.

5 1/6 - 3 2/3=
(5-3) + (1/6 - 2/3)=
2+ (1/6 - (2x2)/(3x2))=
2+ (1/6 - 4/6)
= 2-3/6
= 2- 1/2
= 1 1/2

answer : 3 220 000

meaning u just have to add 0's afta the number given.how many 0's?read the question if ten=0, if hundred=00 and so on..

for example: 432 hundred = 43200, 432 thousands = 432000

hope u understand.. =)
