11/9-3/9 x 4/5=11/9-4/15
=55/45-12/45
=43/45
\(\frac{11}{9}\)- \(\frac{3}{9}x\frac{4}{5}\)= \(\frac{8}{9}\)x \(\frac{4}{5}\)= \(\frac{32}{45}\)
11/9 - 3/9 x 4/5
=11/9 - 4/15
=55/45 - 12/45
=43/45
~ Học tốt ~
\(\frac{11}{9}-\frac{3}{9}×\frac{4}{5}=\frac{11}{9}-\frac{12}{45}=\frac{55}{45}-\frac{12}{45}=\frac{43}{45}\)
11/9 - 3/9 × 4/5 = 11/9 - 4/15
= 55/45 - 12/45
= 43/45
#HOK TỐT
k mk nhé !
\(\frac{11}{9}-\frac{3}{9}.\frac{4}{5}\)
\(=\frac{11}{9}-\frac{12}{45}\)
\(=\frac{11}{9}-\frac{4}{15}\)
\(=\frac{165}{135}-\frac{36}{135}\)
\(=\frac{43}{45}\)
