Answer:


7(11)/(35)

Explanation:


2(5)/(7)+4(3)/(5)

add the whole numbers


2+4=6

combine the fractions


(5)/(7)+(3)/(5)

LCM is 35 because 7 * 5 =35


(5)/(7)=(5\cdot \:5)/(7\cdot \:5)=(25)/(35)


(3)/(5)=(3\cdot \:7)/(5\cdot \:7)=(21)/(35)


(25)/(35)+(21)/(35)=(25+21)/(35)


=(46)/(35)

change the improper fraction into mixed number


6+1(11)/(35)


=7(11)/(35)
