Answer:
0.0128 Km < 14 m < 1583 cm < 17931 mm
Explanation:
The decreasing order of length is :
Kilometer (Km)
Hectameter(Hm)
Decameter(Dam)
Meter(m)
Decimeter(dm)
Centimeter(cm)
Millimeter(mm)
The largest unit is = Km and smallest is =mm
On going down Multiply each time by 10. for example : 1 Km = 10 Hm,
1Km = 100 Hm (10 x10)
1Km = 1000 m(10 x 10x 10)
Convert each number into the smallest unit (i.e mm)
1. 1583 cm to mm
1 cm = 10 mm
1583 cm = 1583 x 10 = 15830 mm
1583 cm = 15830 mm
2. 0.0128 Km to mm
1 Km = 1000000 mm
0.0128 Km = 0.0128 x 1000000 mm
0.0128 Km = 12800 mm
3.17,931 mm = 17,931 mm(already in mm)
4.
14 m to mm
1 m = 1000 mm
14 m = 14 x 1000 mm
= 14000 mm
Now compare :
15830 mm, 12800 mm , 17,931 mm ,14000 mm
Order is :
12800<14000<15830 <17931
So , the correct order is :
0.0128 Km < 14 m < 1583 cm < 17931 mm
