Question

Find the sum of the following a) 7km 5m; 8m 6cm; 4m 9mm

Answer 1

Answer:

Remember

1km =1000m

1m = 100cm

1m = 10^-3m

So,

7km 5m = 7km + 5/1000 km

= 7km + 0.005km

=7.005 km

8m 6cm = 8m + 6/100m

= 8m + 0.06m

= 8.06m

4m 9mm = 4m + 9×10^-3m

=4m + 0.009 m

=4.009m

Answer 2

Answer:

SO, 7km 5m +8m 6cm +4m 9mm

=[7×1000000+5×1000+8×1000+6×100+4×1000+9]mm

=7000000+5000+8000+600+4000+9

=717609
