Help will. Give show work

so first you have too make both of the denominators the same and we know that 4 can become 8 if you multiply it by 2 so you have to multiply it by both the numerator and denominator so

then equation is

7/8 + 2/8

then u have to add 7 + 2 which equals 9 then put it into a fraction so it 9/8 and then u have to make it a mix number which is 1 1/8

hope this helps sorry its super long
