Ritika is comparing the lengths of different rods. Compare them using <, =, > signs.
456 cm ___ 5 m
456 cm < 5 m (since 5 m = 500 cm, and 456 cm < 500 cm)
55 cm + 200 cm ___ 200 cm + 54 cm
55 cm + 200 cm > 200 cm + 54 cm (255 cm > 254 cm)
6 m 5 cm ___ 6 m 50 cm
6 m 5 cm < 6 m 50 cm
2 m 150 cm ___ 3 m 50 cm
2 m 150 cm = 3 m 50 cm (both equal 350 cm)
238 cm ___ 138 cm + 1 m
238 cm = 138 cm + 1 m (both equal 238 cm)
Explanation
(a) Convert 5 m to centimetres: 5 m = 500 cm. Comparing 456 cm with 500 cm, we get 456 < 500. (b) Left side: 55 + 200 = 255 cm. Right side: 200 + 54 = 254 cm. 255 > 254. (c) Both have 6 m, but 5 cm < 50 cm, so 6 m 5 cm is smaller. (d) Left side: 2 m 150 cm = 200 cm + 150 cm = 350 cm. Right side: 3 m 50 cm = 300 cm + 50 cm = 350 cm. Both are equal. (e) Right side: 138 cm + 100 cm = 238 cm. Left side is also 238 cm. They are equal.
