Question

Arrange the following lengths in their increasing magnitude-- (a)1 m,(b) 1 cm ,(c) 1 km , (d) 1mm

Answer 1

Answer:

Solution:

1 m = 100 cm

1 cm = 10 mm

∴ 1 m = 100 × 10 = 1000mm    

Now,  1 km = 1000 m

∴  1 km = (1000 × 100)cm = 100000 cm = (100000 × 10)mm = 1000000mm

So, arranging 1 metre, 1 centimetre, 1 kilometre, 1 millimetre in increasing order we have:

1mm < 10mm < 1000mm < 1000000mm

Or 1 millimetre < 1 centimetre < 1 metre < 1 kilometre
