Srry but I really don't get this and I'm just learning this so can someone help me out-

Answer 1

250 : 150 25 : 15 5:3 . The ratio 5 to 3 is the simplest form of the ratio 250 to 150, and all three ratios are equivalent.

Answer 2

200

Just do 250/100 to find the ratio and then multiply by 80 to find the top number!
