Express as km using decimals:

(a) 8 m

(b) 88 m

(c) 8888 m

(d) 70 km 5 m

(a) We know that,

1000 m = 1 km

Therefore,

8 m = km

= 0.008 km

(b) We know that,

1000 m = 1 km

Therefore,

88 m = km

= 0.088 km

(c) We know that,

1000 m = 1 km

Therefore,

8888 m = km

= 8.888 km

(d) We know that,

1000 m = 1 km

Therefore,

70 km 5 m = (70 + ) km

= 70 + 0.005 km

= 70.005 km
