Question

giúp mình với \(\frac{7}{2}-\frac{5}{2}:x=\frac{1}{7}\)

Answer 1

\(\frac{7}{2}-\frac{5}{2}:x=\frac{1}{7}\)

\(\frac{5}{2}:x=\frac{7}{2}-\frac{1}{7}=\frac{47}{14}\)

\(x=\frac{5}{2}:\frac{47}{14}=\frac{5}{2}.\frac{14}{47}\)

\(x=\frac{35}{47}\)

Answer 2

7/2 -5/2:x=1/7

-5/2:x=-7/2+1/7

-5/2:x=-47/14

x=-5/2:-47/14

x=35/47

Answer 3

60/94 tu rut gon nha

Answer 4

\(\frac{7}{2}-\frac{5}{2}:x=\frac{1}{7}\)

\(\Rightarrow\frac{7}{2}-\frac{1}{7}=\frac{5}{2}:x\)

\(\Rightarrow\frac{5}{2}:x=\frac{24}{7}\)

\(\Rightarrow x=\frac{5}{2}:\frac{24}{7}\)

\(\Rightarrow x=\frac{35}{48}\)

Answer 5

\(\frac{7}{2}\) \(-\) \(\frac{5}{2}\) : x = \(\frac{1}{7}\)

\(\frac{5}{2}\) : x = \(\frac{7}{2}\) \(-\) \(\frac{1}{7}\)

\(\frac{5}{2}\) : x = \(\frac{47}{27}\) 

x = \(\frac{5}{2}\) : \(\frac{47}{27}\)

x = \(\frac{135}{94}\)

Vậy x = \(\frac{135}{94}\)
