Answer 1

Answer:

1. [(-36) ÷ 12] ÷ 3

(-3) ÷ 3 = -1

2. 2 1/5 ÷ 1 1/5

= 11/5 ÷ 6/5

= 11/5 × 5/6

= 11/6

= 1 5/6

3. First five whole numbers =

0, 1 , 2 , 3 , 4

Mean = (0+1+2+3+4)/ 5

= 10/5

= 2

4. i) x = 3

Add 1 on both sides.

x + 1 = 3 + 1

x + 1 = 4

Multiply both sides by 2

(x+1)×2 = 4×2

2x + 2 = 8

ii) x = 3

Add 2 on both sides

x + 2 = 3 +2

x + 2 = 5

Multiply both sides by 3

(x + 2)× 3 = 5×3

3x + 6 = 15

5. i) 1/8 × 100 = 12.5%

ii) 5/4 × 100 = 125%

6. Ratio of 9 m to 27 cm

9 m or 900 cm.

900 : 27 = 100 : 3
