Trả lời:

The entrance of the zoo is at the bus stop.

The bus stop is at the entrance of the zoo.

\(\frac{72}{96}=\frac{72\div24}{96\div24}=\frac{3}{4}\)

72/96 = 72 : 24 / 96 : 24 = 3/4

 lưu ý: 

/ : là ngăn cách phân số 

: chia 

a, \(\frac{5}{11}\times\frac{7}{25}+\frac{15}{11}\times\frac{1}{5}\)

\(=\frac{5}{11}\times\frac{7}{25}+\frac{5}{11}\times\frac{3}{5}\)

\(=\frac{5}{11}\times\left(\frac{7}{25}+\frac{3}{5}\right)\)

\(=\frac{5}{11}\times\frac{22}{25}\)

\(=\frac{2}{5}\)

b, \(\frac{3}{7}\times\frac{25}{19}-\frac{1}{7}\times\frac{18}{19}\)

\(=\frac{1}{7}\times\frac{75}{19}-\frac{1}{7}\times\frac{18}{19}\)

\(=\frac{1}{7}\times\left(\frac{75}{19}-\frac{18}{19}\right)\)

\(=\frac{1}{7}\times3\)

\(=\frac{3}{7}\)

\(\left(1-\frac{1}{2018}\right)\times\left(1-\frac{1}{2019}\right)\times\left(1-\frac{1}{2020}\right)\times\left(1-\frac{1}{2021}\right)\times\left(1-\frac{1}{2022}\right)\)

\(=\frac{2017}{2018}\times\frac{2018}{2019}\times\frac{2019}{2020}\times\frac{2020}{2021}\times\frac{2021}{2022}\)

\(=\frac{2017}{2022}\)

Ta có \(36dm^2=6.6\left(cm\right)\)

\(\Rightarrow\)Độ dài 1 cạnh bể cá là \(6cm\)

Thể tích bể cá hình lập phương là:

 \(V=6.6.6=216\left(dm^3\right)=216l\)

Vậy bể cá đó chứa \(216\)lít nước

\(26\times x=-70-218+390-24.\)

\(26\times x=78\)

x=3

\(24+26\times x-390+218=-70\)

\(26\times x-148=-70\)

\(26\times x=78\)

\(x=3\)

Vậy \(x=3\)
