Hello!
The answer would be Packages A and C
A. 3:$60
B. 1:$20
There are to tell if the two ratios are equivalent (equal).
1. (A. 3:$60)
Divide 3 by 3 and get 1. Then divide $60 by 3 and get $20. Simplifying 3:$60 into 1:$20
OR
2. (B. 1:$20)
Multiply 1 by 3 and get 3. Then multiply $20 by 3 and get $60. Turning 1:$20 into 3:$60
Hope this helped!
