Expressing from Lower Units to Higher Unit -
1) Using decimal notation express in litres :-
a) 6 l 6 dl 7 cl 2 ml
b) 1 l 5 ml
Ans.)
l dl cl ml
6 6 7 2 = 6.672 l
1 0 0 5 = 1.005 l
Here we first arrange the given units in their place value chart, putting the digits in their proper places, taking the vacant places as zero. Then we express the given measure in the same unit ‘l’ by putting a decimal point after the digit (or digits) written under ‘l’ in the place value chart.
2) Using decimal notation express in kl :-
a) 3 kl 5 hl 3 dal 2 l
b) 18 kl 6 hl
Ans.)
kl hl dal l
3 5 3 2 = 3.532 kl
18 6 0 0 = 18.6 kl
Here we first arrange the given units in their place value chart, putting the digits in their proper places, taking the vacant places as zero. Then we express the given measure in the same unit ‘kl’ by putting a decimal point after the digit (or digits) written under ‘kl’ in the place value chart.
