= \(\frac{3}{7}\)x \(\frac{5}{14}\)
= \(\frac{15}{91}\)
học tốt
\(\frac{3}{4}\times\frac{4}{7}\times\frac{5}{14}\)
\(=\frac{3\times4\times5}{4\times7\times14}=\frac{3\times5}{7\times14}=\frac{15}{98}\)
P/s: Máy tính sinh ra để lm j? -_-
\(\frac{3}{4}X\frac{4}{7}X\frac{5}{14}\)
\(=\left(\frac{3}{4}X\frac{4}{7}\right)X\frac{5}{14}\)
\(=\frac{3}{7}X\frac{5}{14}\)
\(=\frac{15}{98}\)
\(\frac{3}{4}.\frac{4}{7}.\frac{5}{14}\)
=\(\frac{3.4.5}{4.7.14}\)
=\(\frac{3.5}{7.14}=\frac{15}{98}\)
