• # question_answer Express as km using decimals: (a) 8m                                       (b) 88 m (c) 8888 m                                 (d) 70 km 5 m

 We know that 1 km = 1000 m So, $1\,\text{m}=\frac{1}{1000}\,\text{km}$ (a)  $8\text{ m}=8\times \frac{1}{1000}\text{km}=0.008\text{ km}$ (b) $88\text{ m}=88\times \frac{1}{1000}\text{km}=0.088\text{ km}$ (c) $8888\text{ m}=8888\times \frac{1}{1000}\text{km}=8.888\text{ km}$ (d) $70\,\,\text{km}\,\,5\,\,\text{m}=70\,\,\text{km}+5\,\,\text{m}$ $=70\,\,\text{km}+\frac{5\times 1}{1000}\text{km}$ x$=(70+0.005)km\,\,=70.005\,km$
