Write a paragraph about 150 words to tell about the changes of your village

\(\dfrac{3}{4}\times\dfrac{1}{5}\times\dfrac{8}{9}=1\times\dfrac{1}{5}\times1=\dfrac{1}{5}\)

\(\dfrac{2}{3}\times\dfrac{10}{21}\times\dfrac{3}{2}=\left(\dfrac{2}{3}\times\dfrac{3}{2}\right)\times\dfrac{10}{21}=\dfrac{6}{6}\times\dfrac{10}{21}=1\times\dfrac{10}{21}=\dfrac{10}{21}\)

a \(\dfrac{20}{7}+\dfrac{15}{8}=\dfrac{160}{56}+\dfrac{105}{56}=\dfrac{265}{56}\)

b \(\dfrac{29}{5}-\dfrac{5}{3}=\dfrac{87}{15}-\dfrac{25}{15}=\dfrac{62}{15}\)

c \(\dfrac{10}{3}\times\dfrac{3}{2}=5\)

\(=14+405-1=418\)

a \(\dfrac{3}{2}\left(\dfrac{4}{7}+\dfrac{3}{7}\right)=\dfrac{3}{2}\times\dfrac{7}{7}=\dfrac{3}{2}\times1=\dfrac{3}{2}\)

b \(\dfrac{17}{5}\times\dfrac{11}{7}+\dfrac{12}{35}=\dfrac{187}{35}+\dfrac{12}{35}=\dfrac{199}{35}\)

My aunt told him that if he was short of money, she could lend him 50 pounds then.

\(8+\left(x-9\right)=125-64\)

\(x-9=125-64-8\)

\(x-9=53\)

\(x=53+9\)

\(x=62\)
