Question Ritika is comparing the lengths of different rods. Compare them using <, =, > signs.
(a) 456 cm ____ 5 m
456 cm = 456 cm
and 5 m = 5 × 100 = 500 cm
Since, 456 cm < 500 cm
So, 456 cm < 5 m
(b) 55 cm + 200 cm ____ 200 cm + 54 cm
Solution:
55 cm + 200 cm = 255 cm
and 200 cm + 54 cm = 254 cm
Since, 255 cm > 254 cm
So, 55 cm + 200 cm > 200 cm + 54 cm
(c) 6 m 5 cm ____ 6 m 50 cm
Solution:
6 m 5 cm = 6 × 100 cm+ 5 cm
= 600 cm + 5 cm = 605 cm
and 6 m 50 cm = 6 × 100 cm + 50 cm
= 600 cm + 50 cm = 650 cm
Since, 605 cm < 650 cm
∴ 6 m 5 cm < 6 m 50 cm.
(d) 2 m 150 cm ____ 3 m 50 cm
Solution:
2 m 150 cm = 2 × 100 cm + 150 cm
= 200 cm + 150 cm = 350 cm
3 m 50 cm = 3 × 100 cm + 50 cm
= 300 cm + 50 cm = 350 cm
Since, 350 cm = 350 cm
So, 2 m 150 cm = 3 m 50 cm
(e) 238 cm ____ 138 cm + 1 m
Solution:
138 cm + 1 m = 138 cm + 100 cm
= 238 cm
Since, 238 cm = 238 cm
So, 238 cm = 138 cm 1 m
