​

Answer 1

Answer:

Subtract 12 m 36 cm from 48 m 57 cm

Solution:

Case 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
