AI GIẢI GIÚP MIK VỚI

Answer 1

=1/2×2/3×3/4×4/5+4/3÷5/3

=1/3×3/5+4/5

=1/5+4/5

=5/5=1

Answer 2

bằng\(\frac{23}{25}\)

Answer 3

=\(\left(1-\frac{1}{2}\right)x\left(1-\frac{1}{3}\right)x\left(1-\frac{1}{4}\right)x\left(1-\frac{1}{5}\right)+\frac{4}{3}:\frac{5}{3}\)

=\(\frac{2-1}{2}x\frac{3-1}{3}x\frac{4-1}{4}x\frac{5-1}{5}+\frac{4}{5}\)

=\(\frac{1}{2}x\frac{2}{3}x\frac{3}{4}x\frac{4}{5}+\frac{4}{5}\)

=\(\frac{1}{5}+\frac{4}{5}\)

=1

Answer 4

= \(\frac{1}{2}\times\frac{2}{3}\times\frac{3}{4}\)\(\times\frac{4}{5}+\frac{4}{5}\)

= 1

Answer 6

( \(1\)-  \(\frac{1}{2}\))  x  ( \(1\) -  \(\frac{1}{3}\) )    x  (  \(1\) -  \(\frac{1}{4}\) )  x  ( \(1\) -  \(\frac{1}{5}\) )  +  \(\frac{4}{3}\):  \(\frac{5}{3}\)

=   \(\frac{1}{2}\) x  \(\frac{2}{3}\) x  \(\frac{3}{4}\) x  \(\frac{4}{5}\) +  \(\frac{4}{3}\) x  \(\frac{3}{5}\)

=     \(\frac{1x2x3x4}{2x3x4x5}\) +   \(\frac{4}{5}\)

=      \(\frac{1}{5}\) +  \(\frac{4}{5}\)

=  \(1\)

Answer 7

\(\left(1-\frac{1}{2}\right)\cdot\left(1-\frac{1}{3}\right)\cdot\left(1-\frac{1}{4}\right)\cdot\left(1-\frac{1}{5}\right)+\frac{4}{3}:\frac{5}{3}\)

\(=\frac{1}{2}\cdot\frac{2}{3}\cdot\frac{3}{4}\cdot\frac{4}{5}+\frac{4}{5}\)

\(=\frac{1}{5}+\frac{4}{5}=1\)
