Answer 2

Answer:

(v) 3.8 kg, 1900 gm

3.8 kg = 3.8 × 1000 gm = 3800 gm

•

• • Ratio = 3.8 Kg / 1900 gm =

3800 gm / 1900 gm =

3800 / 1900 =

1900 × 2 / 1900 × 1

= 2/1 = 2 : 1

(vi) 7 minutes 20 seconds, 5 minutes 6 seconds.

7 minutes 20 seconds = 7 × 60 seconds + 20 seconds

= ( 420 + 20 ) seconds

= 440 seconds

5 minutes 6 seconds = 5 × 60 seconds + 6 seconds

= ( 300 + 6 ) seconds

= 306 seconds

•

• • Ratio = 7 minutes 20 seconds / 5 minutes 6 seconds = 440 seconds / 306 seconds

= 440 / 306

= 2 × 220 / 2 × 153

= 220 / 153

= 220 : 153
