• 18 = 1 x 18
• 18 = 2 x 9
• 18 = 3 x 6
So, the factors of 18 are 1, 2, 3, 6, 9, 18
1. Write down all the factors of 18

a. Range = data terbesar – data terkecil
2. Work Out
a. The range (Jangkauan)
b. Median (Nilai tengah setelah data diurutkan)
1, 9, 3, 4, 7, 13, 10, 1, 7, 8, 7
Range = 13 – 1 = 12
b. Median
1, 1, 3, 4, 7, 7, 7, 8, 9, 10, 13

So, 8 is 20% of 40
3. Calculate 8 as a percentage of 40

4. Complete the number
You are told that
• The only number on the spinner are 1, 6, and 7
• The probability of the spinner landing on a section numbered with a 1 is ¼
• The spinner is equally likely to land on an odd number as it is to land on
an even number (ganjil genap kemungkinannya sama)

Scale: 1 cm to 40 m
a. Work out the actual distance from the
school to the Hospital
b. The bearing of a House from the hospital
is 250o
The bearing of a house from the school is
120o
Mark the position of the house on the map

9. (a) Write down the gradient of the line y = -2x + 5
(b) Complete the table of value for y = -2x + 5
x -1 2 4 6
y 1 -3 -77
Gradient = -2
x = -1 --- y = -2(-1) + 5 = 2 + 5 = 7

a. 24 – 18b = 6.4 – 6.3.b
= 6(4 – 3b)
b. Expand and simply
5b – 3(2x + 3b) = 5b – 6x – 9b
= – 4b – 6x

Kata kunci:
• bilangan yang dikalikan dengan 1 pasti hasilnya adalah
bilangan itu sendiri.
• Sedangkan jika suatu BILANGAN POSITIF dikalikan
dengan BILANGAN KURANG DARI 1 pasti hasilnya adalah
LEBIH KECIL DARI BILANGAN ITU SENDIRI
• 0.67 itu lebih kecil dari 1, jadi 782 x 0.67 hasilnya pasti lebih
kecil dari 782

NUMBER LESS THAN ONE WILL ALWAYS GET
