Answer:

94/35

Explanation:

Least common multiples of 7 and 5.

7*5=35

9/7=9*5/7*5=45/35

7/5=7*7/5*7=49/35

Add the numbers from left to right.

49/35+45/35

49+45=94

=94/35

94/35 is the correct answer.

\bf \cfrac{9}{7}+\cfrac{7}{5}\implies \stackrel{\textit{using the LCD of 35}}{\cfrac{(5)9~~+~~(7)7}{35}}\implies \cfrac{45+49}{35}\implies \cfrac{94}{35}\implies 2(24)/(35)
