Answer:
3a, 13cm 5, 1:200
Step-by-step explanation:
In the question 3 you just have to divide all of those numbers with that 5000, maybe also make them cm so it makes more sense. So 650m = 65000cm:5000= 13cm
then for the question 5, make the km to cm, so 4.2km would be 420000cm. Then you have to divide that 420000cm with the 21 cm, so 420000:21= 200. Then the scale should be 1:200
I had difficulties with these as well. If you need extra help with the task 3 please pm me :)

Answer:
3/9
Step-by-step explanation:
15*4= 60 so 15/60 is equivalent to 1/4.
1/16 is just a smaller equivalent of 2/8 which is just a smaller equivaent of 1/4.
3/9 simplified is 1/3. I/s is bigger than 1/4.
Hope this helps
