ai giup minh som nhat minh se tik

Answer 1

\(\frac{2525}{1717}=\frac{2525:101}{1717:101}=\frac{25}{17}\)

\(\frac{225}{126}=\frac{225:9}{126:9}=\frac{25}{14}\)

Vì 14 < 17

\(=>\frac{25}{14}>\frac{25}{17}=>\frac{2525}{1717}< \frac{225}{126}\)

Answer 2

Kết quả là

   2525/1717 < 225/126

       Đs...

Answer 3

\(\frac{2525}{1717}\)=\(\frac{2525:101}{1717:101}\)=\(\frac{25}{17}\)

\(\frac{225}{126}\)=\(\frac{225:9}{126:9}\)=\(\frac{25}{14}\)

Có 25=25 mà 17<14 nên \(\frac{25}{17}\)<\(\frac{25}{14}\)hay \(\frac{2525}{1717}\)< \(\frac{225}{126}\)

Vậy \(\frac{2525}{1717}\)< \(\frac{225}{126}\)

Answer 4

Mình nhầm chỗ 17 < 14 nha bạn sửa lại 17> 14 mới đúng

Answer 5

Ta có :   \(\frac{2525}{1717}=\frac{2525:101}{1717:101}=\frac{25}{17}\)

               \(\frac{225}{126}=\frac{225:9}{126:9}=\frac{25}{14}\)

 \(Do17>14\Rightarrow\frac{25}{17}< \frac{25}{14}\)

                       \(\Rightarrow\frac{2525}{1717}< \frac{225}{126}\)

Answer 6

Ta có :2525/1717=25/17

225/16=25/14

Có 25/17<25/14

=>2525/1717<225/126

Vậy.............

Answer 7

* Ta có: \(\frac{2525}{1717}=\frac{25.101}{17.101}=\frac{25}{17}\)

             \(\frac{225}{126}=\frac{9.25}{9.14}=\frac{25}{14}\)

Vì \(\frac{25}{17}< \frac{25}{14}\)nên \(\frac{2525}{1717}< \frac{225}{126}\)

Answer 8

Ta thấy:

\(\frac{2525}{1717}=\frac{2525:101}{1717:101}=\frac{25}{17}\)

\(\frac{225}{126}=\frac{225:9}{126:9}=\frac{25}{14}\)

Ta so sánh : \(\frac{25}{17};\frac{25}{14}\)

Vì 17 > 14 => \(\frac{25}{17}< \frac{25}{14}=>\frac{2525}{1717}< \frac{225}{126}\)
