Question

20km ko 17km 50m subtract kare

Answer 1

Minuend and subtrahend are both converted into smaller units.

12 m 36 cm = (12 × 100) cm + 36 cm = (1200 + 36) cm = 1236 cm

48 m 57 cm = (48 × 100) cm + 57 cm = (4800 + 57) cm = 4857 cm

Now subtract

48 m 57 cm = 4857 cm

- 12 m 36 cm = - 1236 cm
3621 cm

= 3600 cm + 21 cm

= 36 m 21 cm

Therefore, 48 m 57 cm - 12 m 36 cm = 36 m 21 cm

Answer 2

20km in meter
20X1000=20000 meters
17km 50 meter in meter
17X1000=17000+50=17050 meters
20000-17050=2950 meters
2950/1000=2.950km or 2km 950 meters
