Answer: 4/9

Explanation:

To find a common denominator we need to multiply the each term by a fractional form of 1 so they have the same denominators (bottom number).


(3)/(10)*(9)/(9)=(27)/(90)


(4)/(9)*(10)/(10)=(40)/(90)

Now we can tell which one is bigger because they share a denominator:


(40)/(90) > (27)/(90)
