Đáp án: $\dfrac{719}{120}$
Giải thích các bước giải:
$-6+\dfrac{5}{12}:2+\dfrac34+11+\dfrac14(\dfrac13-\dfrac15)$
$=(11-6)+\dfrac{5}{12}\cdot\dfrac12+\dfrac34+\dfrac14\cdot\dfrac2{15}$
$=5+\dfrac{5}{24}+\dfrac34+\dfrac1{30}$
$=\dfrac{600}{120}+\dfrac{25}{120}+\dfrac{90}{120}+\dfrac{4}{120}$
$=\dfrac{600+25+90+4}{120}$
$=\dfrac{719}{120}$
