Answer 1

Answer:

(0) 12 km 250 m and 50 km 280 m    [ 1 km = 1000 m]

= 12.250 km + 50. 280 km = 62.53 km

(ii) 5L 500 mLand 7 L 287 mL     [1 L = 1000 mL]

= 5. 5 L + 7.287 L = 12.787 L

(iii) 20 kg 258 g and 6 kg 358 g     [1 kg = 1000g]

= 20.258 kg + 6.358 kg = 26.616 kg

(iv) 130 m 33 cm, 150 m 24 cm and 39m 15 cm     [1 m = 100 cm]

= 130.33 m + 150.24 m + 39.15 m = 319.72 m
