Answer:
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
