Answer:
1:25 (dm:km)
Step-by-step explanation:
For the ratio, you compare two units.
Naturally, we could say that 2 dm corresponds to 50 km
Written in fraction form:

1dm/25km
Just replace the "/" with ":"
1:25 (dm:km)
2.8y+6+0.2y=5y-14
Combine like terms
3y+6=5y-14
Subtract 6 from both sides
3y=5y-20
Subtract 5y from both sides
-2y=-20
Divide both sides by -2
Y=10
