Answer:
Greater than symbol. 
2/3 > 2/4
Explanation:
We have two fractions, 2/3 and 2/4
We then go back to the inequality part of mathematics where we have symbols such as greater than (>), less than (<), and equal to (=). 
Of the three inequality symbols, we look and pick at the one that represents best, the fractions we were given. 
2/3 and 2/4
With 2/3 being greater than 2/4.
2/3 = 0.67
2/4 = 0.50
Succinctly, 2/3 > 2/4.
