chúc bạn học tốt
\(\frac{8}{35}\)+ \(\frac{2}{7}\): \(\frac{2}{4}\)
= \(\frac{8}{35}\)+ \(\frac{4}{7}\)
=\(\frac{196}{245}\)
8/35+2/7:2/4
=8/25+2/7x4/2
=8/35+4/7
=\(\frac{4}{5}\)
bạn Zlatan Ibrahimovic đúng đấy mình nhầm
8/35+4/7
=8/35+20/35
=28/35=4/5
\(\frac{8}{35}+\frac{2}{7}\div\frac{2}{4}\)
\(=\frac{8}{35}+\frac{4}{7}\)
\(=\frac{8}{35}+\frac{20}{35}\)
\(=\frac{28}{35}\)
8/35 + 2/7 : 2/4
= 8/35 + 4/7
= 8/35 + 20/35
= 28/35
\(\frac{8}{35}\)+ \(\frac{2}{7}\): \(\frac{2}{4}\)
=\(\frac{8}{35}\)+ \(\frac{2}{7}\)x \(\frac{4}{2}\)
= \(\frac{8}{35}\)+ \(\frac{2\times4}{7\times2}\)
= \(\frac{8}{35}\)+ \(\frac{4}{7}\)
= \(\frac{8}{35}\)+ \(\frac{20}{35}\)
= \(\frac{28}{35}\)
