1 (4/9) = 13/9... 3 1/3 = 10/3
13/9 + 10/3 you must first have equal denominators (bottom numbers)
13/9 + 30/9 = 43/9 or 4 7/9

Answer:

43/9

Explanation:

The given fraction is


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

Let us convert the mixed fraction into equivalent improper fraction.


1(4)/(9)=(13)/(9)

And, the second fraction becomes


3(1)/(3)=(10)/(3)

Now, we find the LCD. The LCD is 9

Now, we make each denominator equal to LCD, which is 9. So we multiply the numerator and denominator of second fraction with 3.


(13)/(9)+(10*3)/(3*3)\\\\=(13)/(9)+(30)/(9)

Now, since the denominator is equal. Hence, we can directly add numerators.


(13+30)/(9)\\\\=(43)/(9)

Therefore, the simplified expression is 43/9
