\(\frac{5}{8}:x=\frac{3}{4}\)

\(x=\frac{5}{8}:\frac{3}{4}\)

\(x=\frac{5}{6}\)

\(\frac{2}{4}+\frac{3}{4}:\frac{1}{2}\)

\(=\frac{2}{4}+\frac{6}{4}\)

\(\frac{8}{4}=2\)

Hok tốt

A = m x 3 + n x 4 + p x 2 + m + 2 x p

= m x 4 + n x 4 + p x 4

= (m + n + p) x 4

mọi người giúp mình bài

3636/4545+x=4848/1515

x=4848/1515-3636/4545

x=14544/4545-3636/4545

x=10908/4545

3535/5050-x=8/25

x=3535/5050-1616/5050

x=1919/5050

=\(\frac{2001x2004x1001x2006}{2004x2006x2001x2002}\)=\(\frac{1}{2}\)

\(=\frac{2001.2004.1001.2002}{2004.2006.2001.2002}=\frac{1.1.1001.1}{1.2006.1.1}=\frac{1001}{2006}\)

Kết quả bằng 1/2016

=1/2016 do

a) nếu k =1000 thì biểu thưc = 950

b) số lớn nhất có 4 chữ số là:9999

=> k= 9999+50=10049 

a:1000-10*5=1000-50=950

b:9999+(10*5)=10049

đúng thì k tui nhá

1    \(A=\left(1+\frac{1}{2}\right)\times\left(1+\frac{1}{3}\right)\times\left(1+\frac{1}{4}\right)\times.........\times\left(1+\frac{1}{2016}\right)\times\left(1+\frac{1}{2017}\right)\)

\(A=\frac{3}{2}\times\frac{4}{3}\times\frac{5}{4}\times......\times\frac{2016}{2017}\times\frac{2018}{2017}\)

\(A=\frac{2018}{2}=1009\)

\(B=\frac{2}{3.5}+\frac{2}{5.7}+\frac{2}{7.9}+.......+\frac{2}{43.45}\)

\(B=\frac{1}{3}-\frac{1}{5}+\frac{1}{5}-\frac{1}{7}+\frac{1}{7}-......+\frac{1}{43}-\frac{1}{45}\)

\(B=\frac{1}{3}-\frac{1}{45}\)

\(B=\frac{14}{45}\)

2     \(\frac{2017}{2018}\times\frac{23}{47}+\frac{24}{2018}\times\frac{2017}{47}\)

\(=\frac{2017}{2018}\times\frac{23}{47}+\frac{24}{47}\times\frac{2017}{2018}\)

\(=\frac{2017}{2018}\times\left(\frac{23}{47}+\frac{24}{47}\right)\)

\(=\frac{2017}{2018}\times1\)

=\(\frac{2017}{2018}\)

bạn nào xem giải thế có đúng ko
