Question

Addition with conversion.
(a) 3 m 65 cm and 16 m 42 cm (convert to cm)
(b) 8 km 89 m and 22 km 113 m (convert to m)​

Answer 1

Answer:

(a) 2007 , (b) 30202

Step-by-step explanation:

a) 3m = 300 CM, 16m = 1600

-(1m = 100 cm)

so add after converting

= 300+ 65+ 1600+ 42

= 365+ 1600+ 42

= 1965+ 42

= 2007

b) 8km = 8000, 22km= 22000

- ( 1 km = 1000 m)

so add after converting

= 8000+89+22000+113

= 8089+22000+113

= 30089+113

= 30202

Answer 2

ANSWER :-

1) 3 m 65 cm and 16 m 42 cm (convert to cm)

1m = 100cm

So add after converting

300+65+1600+42

365+1600+42

1965+42

2007

=1642 cm

2) 8 km 89 m and 22 km 113 m (convert to m)

1km=1000m

So add after converting

8000 + 89 + 22000 +113

8089 + 22000 + 113

30089 + 113

30202
