Arrange quantities into decreasing order 0.87km,807m,8km7m show working
To compare the quantities, we need to convert them to the same unit (meters) first, and then arrange them in decreasing order:
0.87 km = 0.87 * 1000 = 870 meters
8 km 7 m = 8 * 1000 + 7 = 8000 + 7 = 8007 meters
Now, the quantities in decreasing order are:
8007m, 870m, 807m
