looking common minimum denominator
for 4 and 3 is 12
multiply first fraction by 3 so we have [tex] \frac{3}{4}= \frac{3*3}{4*3}= \frac{9}{12} [/tex]
multiply second fraction by 4 so we have [tex] \frac{2}{3}= \frac{2*4}{3*4}= \frac{8}{12} [/tex]
and now just add both fraction [tex] \frac{9}{12}+ \frac{8}{12}= \frac{17}{12}=1 \frac{5}{12} [/tex]
