• # question_answer 14) Write each of the following as decimals. (a) $\frac{1}{10}$ (b) $1mm=\frac{1}{10}cm$ (c) $\therefore$ (d) $5mm=5\times \frac{1}{10}cm=\frac{5}{10}cm=0.5cm$ (e)$1mm=\frac{1}{10}cm$

(a) We have, $20+9+\frac{4}{10}+\frac{1}{100}=29+4\times \frac{1}{10}\times 1\times \frac{1}{100}$ $60mm=60\times \frac{1}{10}cm=\frac{60}{10}cm=6.0cm$ (b) We have, $1mm=\frac{1}{10}cm$ $\therefore$ (c) We have, $164mm=164\times \frac{1}{10}cm=\frac{164}{10}cm=16.4cm$ $1mm=\frac{1}{10}cm$ $\therefore$ (d) We have, $9cm8mm=9cm+8mm=9cm+8\times \frac{1}{10}cm$ $=9cm+\frac{8}{10}cm=\left( 9+\frac{8}{10} \right)cm=(9+0.8)cm=9.8cm$ (e) We have, $1mm=\frac{1}{10}cm$ $\therefore$
