9/23 + 53/3 + 2/69 + (-15)
\(\dfrac{9}{23}+\dfrac{53}{3}+\dfrac{2}{69}+\left(-15\right)\)
\(=\dfrac{9.3}{23.3}+\dfrac{53.23}{3.23}+\dfrac{2}{69}+\dfrac{-15.69}{1.69}\)
\(=\dfrac{27}{69}+\dfrac{1219}{69}+\dfrac{2}{69}+\dfrac{-345}{69}\)
\(=\dfrac{903}{69}\)
\(=\dfrac{301}{23}\).

\(1\dfrac{13}{15}\) . 0,75 - \((\dfrac{11}{20}\) + 25%) : \(\dfrac{7}{3}\)
Help me!!!! Giúp tớ với ạ🥺👉🏻👈🏻
= 28/15 . 3/4 - ( 11/20 + 1/4 ) : 7/3
= 28/15 . 3/4 - 4/5 : 7/3
= 7/5 - 12/35
= 37/35
= \(\dfrac{28}{15}\) . \(\dfrac{3}{4}\) - (\(\dfrac{11}{20}\) + \(\dfrac{1}{4}\)) : \(\dfrac{7}{3}\)
= \(\dfrac{7}{5}\) - (\(\dfrac{11}{20}\) + \(\dfrac{5}{20}\)) : \(\dfrac{7}{3}\)
= \(\dfrac{7}{5}\) - \(\dfrac{16}{20}\) : \(\dfrac{7}{3}\)
= \(\dfrac{7}{5}\) - \(\dfrac{16}{20}\) x \(\dfrac{3}{7}\)
= \(\dfrac{7}{5}\) - \(\dfrac{12}{35}\)
= \(\dfrac{49}{35}\) - \(\dfrac{12}{35}\)
= \(\dfrac{37}{35}\)
Giúp me🥺🥺
-13/25x9/17+13/17x8/25+(-13/25)
=-13/25x9/17+8/17x13/25+(-13/25)
=13x(-9/17+8/17-1)
=13x(-18/17)=-234
a) Ta có: \(\dfrac{-13}{25}\cdot\dfrac{9}{17}+\dfrac{13}{17}\cdot\dfrac{8}{25}+\dfrac{-13}{25}\)
\(=\dfrac{-13}{25}\cdot\dfrac{9}{17}-\dfrac{-13}{25}\cdot\dfrac{8}{17}+\dfrac{-13}{25}\)
\(=\dfrac{-13}{25}\left(\dfrac{9}{17}-\dfrac{8}{17}+1\right)\)
\(=\dfrac{-13}{25}\cdot\dfrac{18}{17}\)
\(=-\dfrac{234}{425}\)
