9:10 = ___ : 40
the second term (10) was multiplied by 4 to get (40) ... therefore multiply the first term (9) by the same factor of 4 to get (36)
9:10 = 36:40
..............
same goes for the rest...
10:4 = 5: ___
the first term (10) was divided by a factor of 2 to get (5) ... so divide the second term (4) by the same factor of 2 to get (2) ..
10:4 = 5:2
............
you can do the rest in the same way...
good luck!

1. 40 is 4 times 10 so multiply 9 by 4 and get 36
2. 35 is 7 times 5 so multiply 4 by 7 and get 28
3. 3 is 1/3 of 9 so divide 10 by 3 and get 10/3
4. 5 is 1/2 of 10 so divide 4 by 2 and get 2
5. 8 is 4 times 2 so divide 16 by 4 and get 4
6. 25 is 5 times 5 so divide 5 by 5 and get 1
7. 18 is 6 times 3 so divide 24 by 6 and get 4

These are NOT simplest form.. they are ratios...
what you do to the ratio on the left you need to do the the one on the right...
1. 9:10 = _:40.. what you do to the 10 to get 40 you also need to do to the 9.. so.. 10*4=40, 9*4=36 so you get..
9:10 = 36:40...
the rest of them are done in similar manner.

1.
9 / 10 = x / 40, x = 9 / 10 * 40 = 36
You can figure the rest now?
