Rút gọn rồi tính:
\(\frac{28}{35}.\frac{15}{72}.1\frac{7}{49}\)
\(=\frac{4}{5}.\frac{5}{24}.\frac{56}{49}\)
\(=\frac{4.5.8}{5.24.7}=\frac{4}{21}\)
\(\frac{28}{35}.\frac{15}{72}.1\frac{7}{49}\)
\(=\frac{4}{5}.\frac{5}{24}.\frac{7}{49}\)
\(=\frac{4}{21}\)
k mk nha, cảm ơn những người đã k
Bài làm:
\(\frac{28}{35}.\frac{15}{72}.1\frac{7}{49}\)
= \(\frac{4}{5}.\frac{5}{24}.\frac{56}{49}\)
= \(\frac{4.5.8}{5.24.7}\)
= \(\frac{4}{21}\)
✌️ Hok tốt nha bn ✌️
