    mathematic review

    Hello I am new here in Mathhelpforum, I am trying a sample civil service exams (a reviewer)... and then I saw a question like this:
    30% is to 3/5 as 60% is to ____?
    1. 1 1/5 2. 1 3. 3 4. 2 1/3 5. 2

    I figure that 30% = 3/5 because of this solution:
    30/100 divided by 5 = 6/10
    6/10 divided by 2 = 3/5
    (I actually don't remember if the solution is correct)

    but what about 60% if choices involves a whole number and a fraction?

    60% it to 6/5 = 1 and one fifth.

    (30% is half of 3/5, and 60% is half or 1 and 1/5)

    sorry sir I am a bit slow and still not getting the answer... I forgot how to convert fraction into combination of whole number and fraction. Can you show me a solution on how to convert 6/5 to 1 1/5. Thanks in advance

    6/5= (5+1)/5=(5/5)+(1/5)= 1+(1/5) which is one and one fifth
