Solve each of the following.

Contoh
Di sebuah kedai cenderahati, magnet peti sejuk dijual dalam 12 keping sepeket dan penanda buku dijual dalam 18 keping
sepeket. Amar ingin membeli bilangan cenderahati yang sama bagi kedua-dua jenis cenderahati. Cari bilangan peket yang
paling kurang bagi magnet peti sejuk dan penanda buku yang perlu dibeli oleh Amar. TP 4
At a gift shop, fridge magnets are sold in a pack of 12 and bookmarks are sold in a pack of 18. Amar wants to buy the same number of
both types of souvenirs. Find the smallest number of packs of fridge magnets and bookmarks Amar will need to buy.

2 12 , 18 Bilangan setiap jenis cenderahati = 36
Number of each type of souvenirs
3 6 , 9
2 2 , 3 Bilangan peket magnet peti sejuk yang paling kurang
3 1 , 3 Smallest number of packs of fridge magnets = 36 ÷ 12
= 3
1 , 1
GSTK / LCM = 2 × 3 × 2 × 3 Bilangan peket penanda buku yang paling kurang = 36 ÷ 18
= 36 Smallest number of packs of bookmarks
= 2

1. CD (cakera padat) muzik rock dan CD muzik klasikal masing-masing dijual dalam 4 keping dan 6 keping sepeket.
Cik Jumanah ingin membeli bilangan CD yang sama bagi setiap jenis CD itu. Cari bilangan peket yang paling kurang
bagi setiap jenis CD yang perlu dibeli oleh Cik Jumanah.
Rock CDs and classical CDs are sold in a pack of 4 and 6 respectively. Cik Jumanah wants to buy the same number of each type
of CD. Find the smallest number of packs of each type of CD that Cik Jumanah will need to buy. TP 4
2 4 , 6 Bilangan setiap jenis CD = 12
Number of each type of CD
2 2 , 3
3 1 , 3 Bilangan peket CD muzik rock yang paling kurang = 12 ÷ 4
1 , 1 Smallest number of packs of rock CDs
= 3
GSTK / LCM = 2 × 2 × 3
= 12 Bilangan peket CD muzik klasikal yang paling kurang = 12 ÷ 6
Smallest number of packs of classical CDs
= 2

Number of each type of bun
3 3 , 4 , 5
2 1 , 4 , 5 Bilangan bungkus roti coklat yang minimum = 120 ÷ 6
Minimum number of packs of chocolate buns
2 1 , 2 , 5
= 20
5 1 , 1 , 5
1 , 1 , 1 Bilangan bungkus roti kaya yang minimum = 120 ÷ 8
Minimum number of packs of kaya buns
GSTK / LCM = 2 × 3 × 2 × 2 × 5 = 15
= 120 Bilangan bungkus roti sosej yang minimum
