Question

So sánh 2 phân số: \(\frac{-2000}{2010}\)và \(\frac{-2010}{2020}\)

Giải ra giùm mik nha.Đúng mik tik cho

Answer 1

Ta có:

\(\frac{-2010}{2020}=\frac{-2000+\left(-10\right)}{2010+10}=\frac{-2000}{2010}+\frac{-10}{10}=\frac{-2000}{2010}+1\)

Mà \(\frac{-2000}{2010}+1>\frac{-2000}{2010}\)

\(\Rightarrow\frac{-2010}{2020}>\frac{-2000}{2010}\)

                                         Vậy \(\frac{-2010}{2020}>\frac{-2000}{2010}\).

Ai k mình mình k lại.

Answer 2

\(\frac{-2000}{2010}=0,995...\)

\(\frac{-2010}{2020}=0,995049...\)

vay \(\frac{-2000}{2010}<\frac{-2010}{2020}\)
