Answer:

1.) 12:20

6:10

2.) 30:50

6*5=30 and 10*5=50

(6:5 is the proportional relationship)

Step-by-step explanation:

Part A: Since the base numbers are 6:5, you can multiply any number like 5 on both sides. They only have to be the same number.

Part B: Divide the numbers until you cannot any more. I divided them both by 6.
