Answer 1

Answer:

(i) -4/9

(ii) -1/30

(iii) 26/57

(iv) -62/13

Step-by-step explanation:

$(i) \frac{ - 7}{9} + \frac{3}{9} = \frac{ - 7 + 3}{9} = \frac{ - 4}{9} \\ (ii) \frac{ - 3}{10} + \frac{4}{15} = \frac{ - 9 + 8}{30} = \frac{ - 1}{30} \\ (iii) \frac{ - 8}{19} + \frac{ - 2}{57} = \frac{ - 24 - 2}{57} = \frac{26}{57} \\ (iv) \frac{ - 7}{26} + \frac{ - 9}{2} = \frac{ - 7 - 117}{26} = \frac{ - 124}{26} = \frac{ - 62}{13}$

Take LCM ii, iii and iv sum
