Write the numbers given in the following place value table in decimal form.

Hundreds (100)		Tens (10)	Ones (1)	Tenths (1/10)	Hundredths (1/100)	Thousandths (1/1000)
(a)	0	0	3	2	5	0
(b)	1	0	2	6	3	0
(c)	0	3	0	0	2	5
(d)	2	1	1	9	0	2
(e)	0	1	2	2	4	1

Answer:

(a) Here, \[\frac{1}{100}m=0.01m\] \[\frac{1}{100}\] \[100cm=1m\Rightarrow 1cm=\frac{1}{100}m\] (b) Here, \[\therefore \] \[15cm=15\times \frac{1}{100}m=\frac{15}{100}m=0.15m\] \[1cm=\frac{1}{100}m\] (c) Here, \[\therefore \] \[6cm=6\times \frac{1}{100}m=\frac{6}{100}m=0.06m\] \[1cm=\frac{1}{100}m\](d) Here, \[\therefore \] \[2m45cm=2m+45cm=2m+45\times \frac{1}{100}m\] \[=2m+\frac{45}{100}m=2m+0.45m=(2+0.45)m=2.45m\] (e) Here, \[1cm=\frac{1}{100}m\] \[\therefore \] \[9m7cm=9m+7cm=9m+7\times \frac{1}{100}m\]
