Answer:
1. 2/8 = 12/48
2. 18/20 = 99/110
Step-by-step explanation:
If you divide 2 by 8, you get .25. Knowing this, you can just expand it into another form. 12/48 (simplified into 2/8, aka 1/4) would also be .25 if divided. If you divide 18 by 20, you get .9, and same with if you divide 99/110.

2A=1h(a+b)
2A/a+b=h
