a, x : \(\frac{5}{4}\) = \(\frac{9}{5}\) + \(\frac{1}{2}\)
x : \(\frac{5}{4}\) = \(\frac{23}{10}\)
x= \(\frac{23}{10}\) x \(\frac{5}{4}\)
x= \(\frac{23}{8}\)
c, ( x + \(\frac{3}{4}\) ) x \(\frac{5}{7}\) = \(\frac{10}{9}\)
x + \(\frac{3}{4}\) = \(\frac{10}{9}\) : \(\frac{5}{7}\)
x + \(\frac{3}{4}\) = \(\frac{14}{9}\)
x= \(\frac{14}{9}\) - \(\frac{3}{4}\)
x= \(\frac{56}{36}\) - \(\frac{27}{36}\)
x= \(\frac{29}{36}\)
Tk mk nha
\(x:\frac{5}{4}=\frac{9}{5}+\frac{1}{2}\Leftrightarrow x:\frac{5}{4}=\frac{23}{10}\)
\(\Leftrightarrow x=\frac{23}{10}.\frac{5}{4}\Leftrightarrow x=\frac{23}{8}\)
\(\left(x+\frac{3}{4}\right).\frac{5}{7}=\frac{10}{9}\Leftrightarrow x+\frac{3}{4}=\frac{10}{9}:\frac{5}{7}\)
\(\Leftrightarrow x+\frac{3}{4}=\frac{14}{9}\Leftrightarrow x=\frac{14}{9}-\frac{3}{4}\Leftrightarrow x=\frac{29}{36}\)
a) x : 5/4 = 23/10 b) ( x + 3/4 ) x 5/7 = 10/9
x = 23/10 x 5/4 x + 3/4 = 10/9 : 5/7
x = 23/8 x + 3/4 = 14/9
x = 14/9 - 3/4
x = 29/36
