(iii) Six hundred point eight
(iv) Two hundred five and five hundredths
(v) Seven and fifteen thousandths
(i) Above questions can be written as,
= (2 × 1) + (5 × (1/10))
= 2 + 5/10
= 2 + 0.5
= 2.5
(ii) Above questions can be written as,
= (2 × 10) + (9 × (1/10))
= 20 + 9/10
= 20 + 0.9
= 20.9
(iii) Above questions can be written as,
= 600.8
(iv) Above questions can be written as,
= (205) + (5 × (1/100))
= 205 + 5/100
= 205 + 0.05
= 205.05
(v) Above questions can be written as,
= (7 × 1) + (15 × (1/1000))
= 7 + 15/1000
= 7 + 0.015
= 7.015
