a) Because 1000m = 1km so 3576m = 3000m + 576m = 3km + 0,576km = 3,576km.
Do 1000m = 1km nên 3576m = 3000m + 576m = 3km + 0,576km = 3,576km.
So 3576m = 3,576km ;
b) Because 100cm = 1m so 53cm = 0,53m
Do 100cm = 1m nên 53cm = 0,53m
c) Because 1000kg = 5 tons so : 5360kg = 5000kg + 360kg = 5 tons + 0,360 tons = 5,360 tons
Do 1000kg = 5 tấn nên : 5360kg = 5000kg + 360kg = 5 tấn + 0,360 tấn = 5,360 tấn
So 5360kg = 5,360 tons ;
Vậy 5360kg = 5,360tấn ;
d) Because 1000g = 1kg so 657g = 0,657kg ;
Do 1000g = 1kg nên 657g = 0,657kg ;
