1.y=16 x=8 ||| Because the 12 and 9 are the same side, i just decided to go from there, 9 is 75% of 12, so y and x would be
2.d=24 ||| the smaller triangle once again is 75% of the bigger one.
3.x=6 y=60 ||| the smaller triangle is 1/3 of the bigger one.
4. DE=8 AC=20 ||| The smaller triangle is half of the bigger one.
1. 6 is 75% of 8 and 12 is 75% of 16.

3. 18/3=6 and 6 is 1/3 of 18; 20 is 1/3 of 60
4. 10 is 1/2 of 20; 1/2 of 16 is 8
Hope this helps.
