  1. The largest amount is $1.40, and the largest ratio is 7.
    So
    2:4:5:7 = ? : ? : ? :$1.40
    Can you take it from here?

  2. If you multiply 7 by $0.2, you will get $1.40.
    So for the first case, you also multiply 2 by $0.2 to get $0.40.
    2:4:5:7 = $0.40: ? : ? : $1.40
    You can take it from here?
