tim 5 phan so be hon 5 phan 6 va lon hon 5 phan 7
\(\frac{3}{4};\frac{10}{13};\frac{15}{19};\frac{4}{5};\frac{20}{27}\)
Gọi những phân số cần tìm là :x
Ta có : \(\frac{5}{7}=\frac{30}{42}\)
\(\frac{5}{6}=\frac{35}{42}\)
\(\Rightarrow30< 31< 32< 33< 34< 35\)
\(\Rightarrow\frac{30}{42}< \frac{31}{42}< \frac{32}{42}< \frac{33}{42}< \frac{34}{42}< \frac{35}{42}\)
=> 5 phân số \(\frac{5}{7}< x< \frac{5}{6}\)là\(\frac{5}{7}< \frac{31}{42}< \frac{16}{21}< \frac{11}{14}< \frac{17}{21}\)

tim mot phan so lon hon \(\frac{5}{7}\)va be hon \(\frac{6}{7}\)
\(\frac{5.1}{7};\frac{5.2}{7};\frac{5.3}{7};......;\frac{5.9}{7}\) Bạn Tk cho mình nha !!!!!!!!
tim phan so lon hon 5/7 va be hon 6/7
Gọi phân số là x
<=>\(\frac{5}{7}< x< \frac{6}{7}\)
<=> x = \(\frac{11}{14}\)
Vậy phân số đó là: \(\frac{11}{14}\)
5/7=10/14
6/7=12/14
=>10/14>11/14>12/14
Gọi phân số cần tìm là: a
ta có: \(\frac{5}{7}< x< \frac{6}{7}\)
\(\Rightarrow\frac{10}{14}< x< \frac{12}{14}\)
=> x = 11/14
or \(\frac{15}{21}< x< \frac{18}{21}\)
=> x = 16/21 hoặc x = 17/21
