Hình tròn là cái cây nha dúng thì L-I-K-E cho mình nha

\(5.\left(3+1-4\right)=7.\left(3+1-4\right)\)
\(\Rightarrow5=7\)

a) x - \(\frac{1}{8}\)= \(\frac{7}{3}\)x \(\frac{21}{4}\)
x - \(\frac{1}{8}\)= \(\frac{49}{4}\)
x = \(\frac{49}{4}\)+ \(\frac{1}{8}\)
x = 98
b) x : \(\frac{3}{2}\) = \(\frac{1}{4}\)
x = \(\frac{1}{4}\)x \(\frac{3}{2}\)
x = \(\frac{3}{8}\)
c) \(\frac{103}{10}\) - x = \(\frac{4}{5}\)
x = \(\frac{103}{10}\)- \(\frac{4}{5}\)
x = \(\frac{19}{5}\)
d) x = 51 x \(\frac{4}{17}\)
x = \(12\)

A.\(\frac{12}{15}>\frac{8}{15}\)
B.\(\frac{3}{8}< \frac{5}{6}\)
C.\(\frac{6}{7}< \frac{14}{3}\)
D.\(\frac{143}{144}>\frac{99}{100}\)
Nhớ k mình nha

\(\frac{2}{5}=\frac{4}{10}=\frac{16}{40}=\frac{14}{35}\)
\(\frac{60}{84}=\frac{10}{14}=\frac{5}{7}=\frac{25}{35}\)
chúc bn hok tốt
\(\frac{2}{5}=\frac{14}{35}=\frac{14}{x}\Rightarrow x=35\)
\(\frac{60}{84}=\frac{5}{7}=\frac{10}{14}=\frac{x}{14}\Rightarrow x=10\)
\(\frac{60}{84}=\frac{5}{7}=\frac{5}{x}\Rightarrow x=7\)
\(\frac{60}{84}=\frac{5}{7}=\frac{25}{35}=\frac{x}{35}\Rightarrow x=25\)
\(\frac{2}{5}=\frac{2.2}{5.2}=\frac{4}{10}\)
dấu . là dấu nhân nhé bạn
