Question

\(\frac{38}{133}\)va \(\frac{129}{344}\)    đây là so sánh đó nha giúp mình nhé

Answer 1

38/133<129/344

tk nha

Answer 2

Ta có : 

\(1-\frac{38}{133}=\frac{5}{7}\)

\(1-\frac{129}{344}=\frac{5}{8}\)

Vì \(\frac{5}{7}>\frac{5}{8}\) nên \(\frac{38}{133}< \frac{129}{344}\)

Vậy \(\frac{38}{133}< \frac{129}{344}\)

Answer 3

\(\frac{38}{133}=\frac{2}{7}\)

\(\frac{129}{344}=\frac{3}{8}\)

\(\frac{2}{7}=\frac{16}{56}\)  ;   \(\frac{3}{8}=\frac{24}{56}\)

vì \(16< 24\)nên \(\frac{2}{7}< \frac{3}{8}\)

hay \(\frac{38}{133}< \frac{129}{344}\)
