Ta có :
\(\frac{57}{54}:\frac{4}{7}=\frac{57}{54}\times\frac{7}{4}=\frac{399}{216}=\frac{133}{72}\)
~ Ủng hộ nhé
Trả lời :
57 / 54 : 4 / 7
= 133 / 72
Hok tốt nha !
\(\frac{57}{54}:\frac{4}{7}\)
\(=\frac{57}{54}\times\frac{7}{4}\)
\(=\frac{133}{72}\)
chúc bạn học tốt
\(\frac{57}{54}:\frac{4}{7}\)
\(=\frac{57}{54}\times\frac{7}{4}\)
\(=\frac{399}{216}\)
\(=\frac{133}{72}\)
hok tốt
\(\frac{57}{54}\div\frac{4}{7}\)
= \(\frac{57}{54}\times\frac{7}{4}\)
= \(\frac{399}{216}\)
\(\frac{57}{54}:\frac{4}{7}\)
\(=\frac{57}{54}.\frac{7}{4}\)
\(=\frac{57.7}{54.4}\)
\(=\frac{133}{72}\)
