Question 4

Express as km using decimals.

(a) 8 m (b) 88 m (c) 8888 m

(d) 70 km 5 m

Solution 4:

(a) 1 km = 1000 m

1 m = \frac{1}{1000} km

8 m = 8\times\frac{1}{1000}=\frac{8}{1000}=0.008\ km

(b) 1 km = 1000 m

1 m = \frac{1}{1000} km

88 m = 88\times\frac{1}{1000}=\frac{88}{1000}=0.088\ km

(c) 1 km = 1000 m

1 m = \frac{1}{1000} km

8888 m = 8888\times\frac{1}{1000}=\frac{8888}{1000}=8.888\ km

(d) 1 km = 1000 m

1 m = \frac{1}{1000} km

70 km 5 m = 70+\left(5\times\frac{1}{1000}\right)=70+\frac{5}{1000}=70+0.005=70.005\ km
