Answer:
4.5km
Step-by-step explanation:
2cm=1km
9cm=xkm
so to get from 2 to 9 all you do is multiply by 4.5 so do this the km and you will get 4.5km :)
22/400
Divide top and bottom by 2. 2 into 22 is 11 and 2 into 400 is 200.
11/200.
No other number can go into 11 and 200.
= 11/200 in Simplest form.
