Greetings!
The best way to compare fractions is to find the LCM (The Lowest Common Denominator) of each of the fractions. This can be done simply by listing the multiples of the denominators.
Multiples:
3: 3,6,9,12,15,18,21,24,27...210,213
10:10,20,30,40,60,70,80...210,220
6: 6,12,18,24,30,36,42,48...210,216
7: 7,14,21,28,35,42,49...210,217
The LCM is 210:
3*70=210
10*21=210
6*35=210
7*30=210
Now, we must do what we do the denominators to the numerators:
1*70=70
70/210
2*21=42
42/210
1*35=35
=35/210
2*30=60
=60/210
The fraction with the largest numerator has the greatest value; In this case it 1/3 or 70/210.
Hope this helps.

The scale factor is 1/2 or .5 because 200*.5=100 and 100*.5=50 and so on
The coordinates of A(x, y) will be mapped to A'(-x, -y).
A rotation of 180° negates, or changes the sign of, both the x- and y-coordinates of the points.
I think you would do the (change in Y/change in X) so you would put 25 - 15/-10 - (-8) and then your final answer would be -5
