CTET Class I to V 2019 Dec Paper

8500 mm = $\frac{8500}{1000}$ m = 8.5 m
800 cm 8 mm = $\frac{800}{100}+\frac{8}{1000}$ = 8 + 0.008 = 8.008 m.
80 dm 8 cm $=\frac{80}{10}+\frac{8}{100}=8.08\mathit{m}$
8 m = 8 m
Arrangement in decreasing order
= 8.5 m, 8.08 m, 8.008 m and 8 m.
= 8500 mm, 80 dm 8 cm, 800 cm 8 mm, 8 m.
