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
