\(\frac{29}{60}< \frac{4}{9}\)
\(\frac{6}{28}< \frac{101}{400}\)
\(\frac{131313}{393939}=\frac{1}{3}\)
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: \(\frac{131313}{393939}=\frac{13x10101}{39x10101}=\frac{13}{39}=\frac{1}{3}\)
\(\Rightarrow\frac{131313}{393939}=\frac{1}{3}\)
SO SÁNH
a) 4/9 = 28/63
Tìm phân số trung gian
Ta có: 29/60 > 29/63 > 28/63
Vậy 29/60 > 28/63 hay 29/60 > 4/9
b) 6/28 = 96/448
Tìm phân số trung gian
Ta có: 101/400 > 96/400 > 96/448
Vậy 101/400 > 96/448 hay 101/400 > 6/28
c) 131313/393939 = 1/3
Vậy 131313/393939 = 1/3
