Question

Using decimals, express
(i) 4 km 365 m in kilometres
(ii) 5 km 87 m in kilometres
(iii) 3 km 6 m in kilometres
(iv) 270 m in kilometres
(v) 35 m in kilometres
(vi) 6 m in kilometres

Answer 1

(i) 4 km 365 m in kilometres:
4 km + 365 m = 4 km + $\frac{365}{1000}$ km [Since 1 km = 1000 m]
4 km + 0.365 km = 4.365 km

(ii) 5 km 87 m in kilometres:
5 km + 87 m = 5 km + $\frac{87}{1000}$ km [Since 1 km = 1000 m]
5 km + 0.087 km = 5.087 km

(iii) 3 km 6 m in kilometres:
3 km + 6 m = 3 km + $\frac{6}{1000}$ km [Since 1 km = 1000 m]
3 km + 0.006 km = 3.006 km

(iv) 270 m in kilometres:
$\frac{270}{1000}$ km = 0.270 km [Since 1 km = 1000 m]

(v) 35 m in kilometres:
$\frac{35}{1000}$ km = 0.035 km [Since 1 km = 1000 m]

(vi) 6 m in kilometres:
$\frac{6}{1000}$ km = 0.006 km [Since 1 km = 1000 m]
