Giải thích các bước giải:
$5\dfrac{5}{27} + \dfrac{7}{23} + 0,5 \times \dfrac{5}{27} + \dfrac{16}{23}\\=\dfrac{140}{27}+ \dfrac{7}{23}+ \dfrac{5}{54}+ \dfrac{16}{23}\\= \bigg(\dfrac{140}{27} + \dfrac{5}{54}\bigg)+ \bigg(\dfrac{7}{23}+ \dfrac{16}{23}\bigg)\\= \bigg(\dfrac{280}{54}+\dfrac{5}{54}\bigg) + 1\\= \dfrac{95}{18}+1=\dfrac{113}{18}$
