Write each of the following as decimals:

(a) seven-tenths

(b) Two tens and nine tenths

(c) Fourteen point six.

(d) One hundred and two-ones

(e) Six hundred point eight.

Answer:

(a) 7-tenths \[=\frac{7\times 1}{10}=\text{ }0.7\]

(b) Two tens and 9-tenths

\[(2\times 10)+\left( 9\times \frac{1}{10} \right)=20+\frac{9}{10}\]

\[=20.9\]

(c) Fourteen point six \[=14.6\]

(d) One hundred and 2-ones

\[=(1\times 100)+(0\times 10)+(2\times 1)+(0\times \frac{1}{10})\]

(e) Six hundred point eight = 600.8.
