Đáp án:
Giải thích các bước giải:
`5/6 ± 3/2 × 4/5`
`= 5/6 + 6/5`
`= 61/31`
`6/7 ÷ 9/4 – 1`
`= 8/21 – 1`
`= -13/21`
$\dfrac{5}{6}+$ $\dfrac{3}{2}$ x $\dfrac{4}{5}=$ $\dfrac{5}{6}+$ $\dfrac{6}{5}=$ $\dfrac{25}{30}+$ $\dfrac{36}{30}=$ $\dfrac{61}{30}$
$\dfrac{6}{7}:$ $\dfrac{9}{4}-1=$ $\dfrac{8}{21}-1=$ $\dfrac{8}{21}-$ $\dfrac{21}{21}=$ $-\dfrac{13}{21}$
