Question

3/11 x 7/19 + 3/11 x 17/19 - 3/11 x 24/19

Answer 1

3/11x7/19+3/11x17/19-3/11x24/19

=3/11x(7/19+17/19-24/19)

=3/11x0

=0

Answer 2

Bài làm

\(\frac{3}{11}\times\frac{7}{19}+\frac{3}{11}\times\frac{17}{19}-\frac{3}{11}\times\frac{24}{19}\)

\(=\frac{3}{11}\times\left(\frac{7}{19}+\frac{17}{19}-\frac{24}{19}\right)\)

\(=\frac{3}{11}\times\frac{0}{19}\)

\(=\frac{3}{11}\times0\)

\(=0\)

Answer 3

\(\frac{3}{11}\)x \(\frac{7}{19}\)+ \(\frac{3}{11}\)x \(\frac{17}{19}\)- \(\frac{3}{11}\)x \(\frac{24}{19}\)

= \(\frac{3}{11}\)x (\(\frac{7}{19}\)+ \(\frac{17}{19}\)- \(\frac{24}{19}\))

= \(\frac{3}{11}\)x 0

= 0

Answer 4

Trl

3 / 11 x 7 / 19 + 3 / 11 x 17 / 19 - 3 / 11 x 24 / 19

= \(\frac{3}{11}\) x  ( 7 / 19 + 11 / 19 - 24 / 19 )

=  \(\frac{3}{11}\) x \(\frac{-6}{19}\)

= \(\frac{-18}{209}\)

Answer 5

\(\frac{3}{11}\times\frac{7}{19}+\frac{3}{11}\times\frac{17}{19}-\frac{3}{11}\times\frac{24}{19}\)

\(=\frac{3}{11}\times\left(\frac{7}{19}+\frac{17}{19}-\frac{24}{19}\right)\)

\(=\frac{3}{11}\times0\)

\(=0\)
