It is not written correctly. You need another left-parenthes. You at least should recognize that lowest common denominator is 12.

Depending on what you really have, grouping symbols may not matter.

Hints:
Get each denominator to the LCD, which in this case is 12.
For instance we multiply top and bottom of 3/4 by 3 to get to 9/12

3/4 = (3*3)/(4*3) = 9/12
2/3 = (2*4)/(3*4) = 8/12
1/2 = (1*6)/(2*6) = 6/12
1/3 = (1*4)/(3*4) = 4/12

In short,
3/4 = 9/12
2/3 = 8/12
1/2 = 6/12
1/3 = 4/12

To see why something like 3/4 = 9/12 is the case, draw a circle and split it into quarters. Shade 3 of them to represent 3/4.
Then split each slice into 3 equal pieces. That gives 4*3 = 12 smaller slices total. 9 of which are shaded.

Similar situations occur for the other fractions.
