Answer 2

Answer:

1. 1:2
2. 3:4
3. 0.7:0.4
4. 0.75:1
5. 3:20

Step-by-step explanation:

1) 20:40=20/40= 2/4 = 1/2 = 1:2

2) 81:108= 81/108 = 9/12 = 3/4= 3:4

3) 2.1m:1.2m = 2.1m/1.2m = 0.7/0.4 = 0.7m:0.4m

4) 1mm= 1/10 cm

therefore, 15mm= 1.5cm

1.5cm:2cm=1.5cm/2 cm= 0.75/1= 0.75:1

5) 1 rupee = 100 paisa

therefore 4 rupee = 4 x 100

= 400 paisa

60 p:400 p = 60p/400p = 6p/40p = 3p /20p = 3 paisa:20paisa

(p= paisa)
