15/8-4/9x6/8+1/6=

7/15+(5/6-1/3)=

Answer 1

= 3/4 : 5/8 = 6/5

= 15/8 - 1/3 + 1/6 = 37/24 + 1/6 = 41/23

= 7/15 + 1/2 = 29/30

mk có giải cho bạn lần trc rồi ạ!! bạn xem lại đi ạ ;-;"

Answer 2

\(\dfrac{4}{7}x\dfrac{21}{6}x\dfrac{8}{5}=\dfrac{16}{5}\)

\(\dfrac{15}{8}-\dfrac{4}{9}x\dfrac{6}{8}+\dfrac{1}{6}=\dfrac{41}{24}\)

\(\dfrac{7}{15}+\left(\dfrac{5}{6}-\dfrac{1}{3}\right)=\dfrac{29}{30}\)
