Question

So sánh mà không cần tính \(\frac{2015}{1000}v\text{à}\frac{3030}{2015}\)

Answer 1

Ta có:

\(\frac{2015}{1000}=\frac{1000}{1000}+\frac{1015}{1000}=1+\frac{1015}{1000}\)

\(\frac{3030}{2015}=\frac{2015}{2015}+\frac{1015}{2015}=1+\frac{1015}{2015}\)

Vì \(\frac{1015}{1000}>\frac{1015}{2015}\)

=> \(\frac{2015}{1000}>\frac{3030}{2015}\)

Answer 2

\(\frac{2015}{1000}=2+\frac{15}{1000}\)

\(\frac{3030}{2015}=1+\frac{1015}{2015}\)

suy ra \(\frac{2015}{1000}>\frac{3030}{2015}\)

Answer 3

\(\frac{2015}{1000}>\frac{3030}{2015}\)

Answer 4

Ta có:

\(\frac{2015}{1000}-1=\frac{1015}{1000}\)

\(\frac{3030}{2015}-1=\frac{1015}{2015}\)

Vì \(\frac{1015}{1000}>\frac{1015}{2015}\) nên \(\frac{2015}{1000}>\frac{3030}{2015}\)
