today we did a do now the problem was 3 5/7+4 2/3 so what i did was that i turned both of the mixed numbers into improper fractions and then once i turned them into improper fractions i had to find the LCD of the 2 denominators then i would do equivallent  fractions to the improper fractions like 3 5/7=26/7 that is an improper fraction then the other would be 14/3 then the LCD would be 21 becuase 7x3=21 so thats the LCD then i would do equivalent fractions to the improper fractions like 26/7and /21 and 7x3=21 so what you do to the top you do to the bottom. unfourtuneately i got it wrong i missed one part of it.
