73km 47hm 2dam - 11km 55hm

zvonat [6]

<u>Answer</u>

6,122 hm

<u>Explanation</u>

You can carry out operations on the like terms only. So convert all units to one unit.

I will convert them to dam

1 km =100 dam

73 km = 73 × 100

=7,300 dam

11 km = 11× 100

1100 dam

1 hm = 10 dam

47 hm = 47 × 10

= 470 dam

55 hm = 55× 10

= 550 dam

73km 47hm 2dam - 11km 55hm = (7300+ 470+2) - (1100+550)

= 7,772 - 1,650

= 6,122 hm
