Expressing from Higher Unit to Lower Units -
1) Express in m, dm, cm and mm :
a) 8.425 m
b) 0.6 m
m dm cm mm
7.586 m = 7 5 8 6 = 7 m 5 dm 8 cm 6 mm
0.8 m = 0 8 0 0 = 8 dm
Here we arrange the digits of the given measure in the place value chart (excluding the decimal point), putting the digits in their proper places (starting from ‘m’ and following the place value chart), taking the vacant places as zero. The integral part of the given measure (the part before the decimal point) is together placed under ‘m’ and the decimal part of the given measure (the part after the decimal point) is placed one digit each under ‘dm’, ‘cm’ and ‘mm’.
2) Express in km, hm, dam and m :
a) 2.355 km
b) 30.750 km
km hm dam m
2.355 km = 2 3 5 5 = 2 km 3 hm 5 dam 5 m
30.75 km = 30 7 5 0 = 30 km 7 hm 5 dam
