Question 5

i) 0.04

Solution:
= 0+0.04

= 0+4 hundredths

= 0+4100

=125

ii)

Solution:
2.34

= 2+0.34

= 2+34 hundredths

=2+34100

=2(100100) + 34100

= 200100+34100

= 234100

= 11750

iii)

0.342

= 0+342 thousandths

= 3421000

= 171500

iv) 1.20

= 1+0.20

= 1+20hundredths

= 1+20100

= 100100+20100

= 120100

= 65

v) 17.38

= 17+0.38

= 17+38 hundredths

= 17+38100

= 17(100100) +38100

= 1700100+38100

= 1738100

= 86950
