• 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

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

x = 3y

2x + y = 28

2x + y = 28

karena x = 3y

maka

2(3y) + y = 28

6y + y = 28

7y = 28

y = 4

x = 3yx = 3 . 4

x = 12

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
