\(\frac{7}{29}+\frac{17}{11}+\frac{22}{29}+\frac{5}{11}\)
\(=\left(\frac{7}{29}+\frac{22}{29}\right)+\left(\frac{17}{11}+\frac{5}{11}\right)\)
\(=\frac{29}{29}+\frac{22}{11}\)
\(=1+2\)
\(=3\)
a ,Ta có : 14/25 < 15/25 = 3/5
Ta có : 1 - 3/5 = 2/5
1 - 5/7 = 2/7
Nên 2/5 > 2/7
Vậy 14/25 < 5/7
a,\(\frac{16}{27}\)> \(\frac{15}{29}\)
b,\(\frac{26}{50}\)> \(\frac{14}{29}\)
c,\(\frac{327}{326}\)< \(\frac{326}{325}\)
Tk nha!!
\(a,\frac{16}{27}>\frac{15}{29}\)
\(b,\frac{26}{50}>\frac{14}{29}\)
\(c,\frac{327}{326}< \frac{326}{325}\)

\(\frac{5}{3}\)x 2 + x : \(\frac{4}{3}\)= \(\frac{29}{7}\)
\(\frac{10}{3}\)+ x : \(\frac{4}{3}\)= \(\frac{29}{7}\)
x : \(\frac{4}{3}\)= \(\frac{29}{7}\)- \(\frac{10}{3}\)
x = \(\frac{17}{21}\)x \(\frac{4}{3}\)
x = \(\frac{68}{63}\)
\(\frac{10}{3}+\frac{x.3}{4}=\frac{29}{7}\)
\(\frac{3x}{4}=\frac{29}{7}-\frac{10}{3}=\frac{17}{21}\)
\(x=\frac{68}{63}\)
\(\frac{3}{7}\cdot\frac{14}{29}\cdot\frac{9}{10}=\frac{3\cdot14\cdot9}{7\cdot29\cdot10}\)
\(=\frac{3\cdot2\cdot7\cdot9}{7\cdot29\cdot5\cdot2}=\frac{3\cdot9}{29\cdot5}=\frac{27}{145}\)
\(\frac{3}{7}\times\frac{14}{29}\times\frac{9}{10}=\frac{3\times14\times9}{7\times29\times10}=\frac{378}{2030}=\frac{27}{145}\)
\(\frac{8}{5}-\frac{18}{27}\)
\(=\frac{8}{5}-\frac{2}{3}\)
\(=\frac{24}{15}-\frac{10}{15}\)
\(=\frac{14}{15}\)
\(\frac{12}{20}-\frac{6}{18}\)
\(=\frac{3}{5}-\frac{1}{3}\)
\(=\frac{9}{15}-\frac{5}{15}\)
\(=\frac{4}{15}\)
\(\frac{8}{24}-\frac{5}{25}\)
\(=\frac{1}{3}-\frac{1}{5}\)
\(=\frac{5}{15}-\frac{3}{15}\)
\(=\frac{2}{15}\)
\(\frac{18}{21}-\frac{12}{27}\)
\(=\frac{6}{7}-\frac{4}{9}\)
\(=\frac{54}{63}-\frac{28}{63}\)
\(=\frac{26}{63}\)
1)8/5-2/3=14/15
2)3/5-1/3=4/15
3)1/3-1/5=2/15
4)6/7-4/9=26/63
\(\frac{12}{20}\)= \(\frac{6}{10}\)= \(\frac{3}{5}\)
\(\frac{3}{4}\)= \(\frac{9}{12}\)= \(\frac{12}{16}\)= \(\frac{15}{20}\)
\(\frac{75}{45}\)= \(\frac{15}{9}\)= \(\frac{5}{3}\)
\(\frac{3}{4}\)= \(\frac{18}{24}\)= \(\frac{12}{16}\)
12/20 = 6/10 = 3/5
3/4 = 9/12 = 12/16 = 15/20
75/45 = 15/9 = 5/3
3/4 = 18/24 = 12/16
Tk mk nha
=2 bạn nhé. nhớ cho mình
chúc bạn học tốt
đáp án là 2 k mình đúng đi
