Question

3. Convert into kilometres (in decimals):
(a) 4m
(b) 40 m
(e) 4 km 3 m (0) 18 km 159 m
(c) 76 m
(g) 7 km 49 m
(d) 952 m
(h) 17500 dm
​

Answer 1

Answer:

since 1km=1000m

so 1m= 0.001km

(a) 4m = 4×0.001=0.004km

(b) 40m= 0.040km

(c) 76m = 0.076km

(d)952m= 0.952km

(e) 4km 3m = 4+0.003= 4.003km

(0) 18km 159m= 18+0.159=18.159km

(g) 7km 49m= 7+0.049= 7.049km

(h) 17500dm = since 1 decameter is equal to 0.01km

so 17500= 175 km
