b, 6/28 và 101/400

c,131313/393939 và 1/3

Answer 1

[Khánh Vy]

\(\frac{29}{60}< \frac{4}{9}\)

\(\frac{6}{28}< \frac{101}{400}\)

\(\frac{131313}{393939}=\frac{1}{3}\)

Answer 2

[I don't need you]

a) ta có: \(\frac{29}{60}=0,483;\frac{4}{9}=0,44\)

\(\Rightarrow0,483>0,44\Rightarrow\frac{29}{60}>\frac{4}{9}\)

b) ta có: \(\frac{6}{28}=\frac{3}{14}=0,21;\frac{101}{400}=0,25\)

\(\Rightarrow0,21< 0,25\Rightarrow\frac{6}{28}< \frac{101}{400}\)

c) ta có: \(\frac{131313}{393939}=\frac{13x10101}{39x10101}=\frac{13}{39}=\frac{1}{3}\)

\(\Rightarrow\frac{131313}{393939}=\frac{1}{3}\)
