    2/5/3 means 2 divided by 5 then divided by 3. In other words, we're dividing 2 by 5 first, then by 3. This is the same as dividing by 5*3 all at once. So 2/5/3 = 2/15.

    Now you have

    2/5 + 2/15. To add these, you have to get a common denominator. 15 is 5*3, so we can multiply both the top and bottom of 2/5 by 3.

    (3/3)(2/5) = (3*2)/(3*5) = 6/15

    Now add 2/15

    6/15 + 2/15 = 8/15.

    2/5 + (2/5)*1/3

    = 6/15 + 2/15 = 8/15

    Do division in order that you read them.

    Therefore, it would be two divided by five, then add that to the following: two divided by five, then divide that by three. Therefore, it would 2/5 (which is 0.4) plus 2/5 divided by 3, or (0.4/3). This turns out to be 2/5 + 2/15, or 6/15 + 2/15, or 8/15, which is approximately equal to 0.533333...

    2/5 + 2 / (5/3)

    2/5 + 2(3/5)

    2/5 + 6/5

    8/5

    1 3/5
