Step-by-step explanation:

Given  

निम्नलिखित में से किसमें लम्बाइयों को घटते क्रम में व्यवस्थित किया गया है? (1) 8 m, 80 dm 8 cm, 8500 mm, 800 cm 8 mm (2) 8500 mm, 80 dm

In which of the following are the lengths arranged in decreasing order?

  • Now we need to find the given values in descending order. It will be the second option. That is  
  • 8500 mm, 80 dm 8 cm, 800 cm 8 mm, 8 m
  • Now we need to convert the value to metre.
  • We know that 1 mm = 0.001 m
  •                        1 dm = 0.1 m
  •                        1 cm = 0.01 m
  • So 8500 mm = 8.5 m
  • 80 dm 8 cm = 8 + 0.01 = 8.01 m
  • 800 cm 8 mm = 8 + 0.008 = 8.008 m
  • Finally it is 8 m

Now decreasing order will be 8.5, 8.08, 8.008, 8
