 Mai e kiểm tra mn giúp e nhé ! 

Gọi số học sinh của các lớp 7A, 7B, 7C lần lượt là a, b, c (học sinh)

Theo đề bài:  \(\dfrac{2}{3}\)a=\(\dfrac{8}{11}\)b=\(\dfrac{4}{5}\)c

⇒\(\dfrac{a}{\dfrac{3}{2}}\)=\(\dfrac{b}{\dfrac{11}{8}}\)=\(\dfrac{c}{\dfrac{5}{4}}\)

Áp dụng tính chất dãy tỉ số bằng nhau

⇒\(\dfrac{a}{\dfrac{3}{2}}\)=\(\dfrac{b}{\dfrac{11}{8}}\)=\(\dfrac{c}{\dfrac{5}{4}}\)=\(\dfrac{b+c-a}{\dfrac{11}{8}+\dfrac{5}{4}-\dfrac{3}{2}}\)=\(\dfrac{18}{\dfrac{9}{8}}\)=16

⇒ a = 24

    b = 22

    c = 20

   Vậy số học sinh của các lớp 7A, 7B, 7C lần lượt là 24, 22, 20 (học sinh)

|x-\(\dfrac{1}{3}\)|+\(\dfrac{4}{5}\)=|(\(\dfrac{-16}{5}\))+\(\dfrac{2}{5}\)|

⇒|x-\(\dfrac{1}{3}\)|+\(\dfrac{4}{5}\)=|\(\dfrac{-14}{5}\)|

⇒|x-\(\dfrac{1}{3}\)|+\(\dfrac{4}{5}\)=\(\dfrac{14}{5}\)

⇒|x-\(\dfrac{1}{3}\)|=\(\dfrac{14}{5}\)-\(\dfrac{4}{5}\)

⇒|x-\(\dfrac{1}{3}\)|=2

⇒x-\(\dfrac{1}{3}\)=2⇒x=\(\dfrac{7}{3}\)

hoặc

⇒x-\(\dfrac{1}{3}\)=-2⇒x=\(\dfrac{-5}{3}\)

Vậy x=\(\dfrac{7}{3}\) hoặc x=\(\dfrac{-5}{3}\)

\(\dfrac{-5}{3}\)

x-2=3+75

x-2=78

x=78+2

x=80

Đáp số: x=80
