7,425 : 4,5 + 47,028 × 20,6

= 1,65 + 968, 7768

= 970, 4268

7,425:4,5+47,028x20,6

=1,63+968,7768

=9704068

Ta có: \(1-\frac{2011}{2012}=\frac{1}{2012}\)

          \(1-\frac{2013}{2014}=\frac{1}{2014}\)

Có: \(\frac{1}{2012}>\frac{1}{2014}\)

\(\Rightarrow\frac{2011}{2012}< \frac{2013}{2014}\)

Mk so sánh khoảng cách của các số đến 1. 

\(1-\frac{2011}{2012}=\frac{1}{2012}\)

\(1-\frac{2013}{2014}=\frac{1}{2014}\)

Vì: \(2012< 2014\) nên \(\frac{2011}{2012}< \frac{2013}{2014}\)

72 + 36 * 2 + 24 * 3 + 18 * 4 + 12 + 6 + 168

= 72 + 72 + 72 + 72 + 12 + 6 + 168

= 72 * 4 + 12 + 6 + 168

= 288 + 12 + 6 + 168

= 474

Chúc bạn học tốt! ^_^

72+36x2+24x3+18x4+12+6+168

=72+72+72+72+12+6+168

=474

Đề?

\(C=\frac{2}{1.7}+\frac{2}{7.13}+...+\frac{2}{601.607}\)

\(C=\frac{2}{6}.\left(1-\frac{1}{7}+\frac{1}{7}-\frac{1}{13}+...+\frac{1}{601}-\frac{1}{607}\right)\)

\(C=\frac{1}{3}.\left(1-\frac{1}{607}\right)\)

\(C=\frac{1}{3}.\frac{606}{607}\)

\(C=\frac{202}{607}\)
