Question

Rút gọn phô sấn(phân số)

a)\(\frac{765}{900}\) b)\(\frac{3^5.2^4}{8.36}\) c)\(\frac{84.45}{49.54}\)

Answer 1

a)\(\frac{765}{900}\)

\(=\frac{5.9.17}{5.9.20}=\frac{17}{20}\)

b)\(\frac{3^5.2^4}{8.36}\)

\(=\frac{3^5.2^4}{2^3.3^6}=\frac{2}{3}\)

c)\(\frac{84.45}{49.54}\)

\(=\frac{7.12.5.9}{7.7.6.9}=\frac{7.6.2.5.9}{7.7.6.9}=\frac{10}{7}\)
