Question

Rút gọn rồi so sánh hai phân số:\(\frac{2279}{3127}\)và \(\frac{3337}{4473}\)

Answer 1

2279/3127 = 43/59

3337/4473 = 47/63

43/59 = 2709/3717

47/63 = 2962/3717

suy ra 2962/3717 > 2709/3717

          3337/4473 > 2279/3127

k mik nha ^^

Answer 2

\(\frac{2279}{3127}\)=   \(\frac{43}{59}\)

\(\frac{3337}{4473}\)=    \(\frac{43}{59}\)  mà \(\frac{43}{59}\)= \(\frac{43}{59}\)  =>\(\frac{2279}{3127}\)=    \(\frac{3337}{4473}\)

Answer 3

Rút gọn : 

\(\frac{2279}{3127}=\frac{2279:53}{3127:53}=\frac{43}{59}\)

\(\frac{3337}{4473}=\frac{3337:71}{4473:71}=\frac{47}{63}\)

Rồi bạn quy đồng rồi so sánh nha ! 

tk ủng hộ mk nhé !!!!!!!!!!!

Answer 4

\(\frac{2279}{3127}=\frac{2279:53}{3127:53}=\frac{43}{59}\)

\(\frac{3337}{4473}=\frac{3337:71}{4473:71}=\frac{47}{63}\)

\(\frac{43}{59}=1-\frac{6}{59}\)

\(\frac{47}{63}=1-\frac{6}{63}\)

Mà \(\frac{6}{59}>\frac{6}{63}\Rightarrow\frac{2279}{3127}< \frac{3337}{4473}\)
