Question

Find the sum:
(i) $\frac{5}{4}$+(-$\frac{11}{4}$)
(ii) $\frac{5}{3}$+$\frac{3}{5}$
(iii) -$\frac{9}{10}$+$\frac{22}{15}$
(iv) $\frac{-3}{-11}$+$\frac{5}{9}$
(v)$-\frac{8}{19}$+$\frac{(-2)}{57}$
(vi) $-\frac{2}{3}$+0
(vii) $-\frac{21}{3}$+$\frac{43}{5}$

Answer 1

(i) $\frac{5}{4}$+($-\frac{11}{4}$)
= 5-$\frac{11}{4}$
= -$\frac{6}{4}$
= -$\frac{3}{2}$

(ii) $\frac{5}{3}$+$\frac{3}{5}$
= L.C.M of 3 and 5 is 15
$\frac{5}{3}$+$\frac{3}{5}$= $\frac{25}{15}$+$\frac{9}{15}$= $\frac{25+9}{15}$=$\frac{34}{15}$
