Question

\(1\dfrac{13}{15}\) . 0,75 - \((\dfrac{11}{20}\) + 25%) : \(\dfrac{7}{3}\)

Help me!!!! Giúp tớ với ạ🥺👉🏻👈🏻

Answer 1

= 28/15 . 3/4 - ( 11/20 + 1/4 ) : 7/3

= 28/15 . 3/4 - 4/5 : 7/3

= 7/5 - 12/35

= 37/35

Answer 2

= \(\dfrac{28}{15}\) . \(\dfrac{3}{4}\) - (\(\dfrac{11}{20}\) + \(\dfrac{1}{4}\)) : \(\dfrac{7}{3}\)

= \(\dfrac{7}{5}\) - (\(\dfrac{11}{20}\) + \(\dfrac{5}{20}\)) : \(\dfrac{7}{3}\)

=  \(\dfrac{7}{5}\) - \(\dfrac{16}{20}\) : \(\dfrac{7}{3}\)

=  \(\dfrac{7}{5}\) - \(\dfrac{16}{20}\) x \(\dfrac{3}{7}\)

=  \(\dfrac{7}{5}\) - \(\dfrac{12}{35}\)

=  \(\dfrac{49}{35}\) - \(\dfrac{12}{35}\)

= \(\dfrac{37}{35}\)
