Answer:
3/7 + -4/9 - -11/7 - 7/9
First, make all the denominators equal by finding LCM
LCM of 7,9 = 63.
Next, multiply all the fractions by the number required to make their denominator equal
3/7 = 27/63
-4/9= -28/63
-11/7= -99/63
7/9= 49/63
now, apply the operations
27/63 + (-28/63) - (-99/63) - 49/63
= 27/63 - 28/63 +99/63 - 49/63
= -1/63 +99/63 -49/63
= 98/63 - 49/63
= 49/63
Reduce to lowest form:
= 7/9
