Well, you have to get a lot better at math if you plan on going to college. This is how that problem would be solved by a college student. Do work in parentheses first.

4 1/3 + 2* ( 3*3/5)+5

------Drop all that grade school notation. This is how this should look.

4 1/3 + 2(3 * 3/5) + 5

4 1/3 + 2(9/5) + 5

4 1/3 + 18/5 + 5

------change all to fractions.

13/3 + 18/5 + 5  (15 is common denominator--use form of one to convert )

5*13/5*3 = 65/15

3*18/3*5 = 54/15

5 = 75/15

------thus,

65/15 + 54/15 + 75/15

= 194/15

( 12 14/15 if you are in 5th grade )======Which is the exact form you will show in your college work.. From college algebra to calculus fractions will plague you unless you learn how to handle them.

I guess you're just looking for an answer, rather than help.

Not cool.
