\(y:\frac{5}{2}=\frac{7}{4}:\frac{7}{3}\)
\(y:\frac{5}{2}=\frac{3}{4}\)
\(y=\frac{3}{4}.\frac{5}{2}\)
\(y=\frac{15}{8}\)
Vậy \(y=\frac{15}{8}\)
Chúc bạn zui ~^^
\(y:\frac{5}{2}=\frac{7}{4}:\frac{7}{3}\)
\(y:\frac{5}{2}=\frac{3}{4}\)
\(y=\frac{3}{4}\cdot\frac{5}{2}\)
\(y=1.875\)
Vậy y = 1.875
Theo bài ra,ta có:
\(y:\frac{5}{2}=\frac{7}{4}:\frac{7}{3}\)
=>\(y\cdot\frac{2}{5}=\frac{7}{4}\cdot\frac{3}{4}\)
=>\(y=\frac{3}{4}:\frac{2}{5}=\frac{3}{4}\cdot\frac{5}{2}=\frac{3\cdot5}{4\cdot2}=\frac{15}{8}\)
Vậy y=15/8
\(y:2\frac{1}{2}=1\frac{3}{4}:2\frac{1}{3}\)
\(y:\frac{5}{2}=\frac{7}{4}:\frac{7}{3}\)
\(y:\frac{5}{2}=\frac{3}{4}\)
\(y=\frac{3}{4}.\frac{5}{2}\)
\(y=\frac{15}{8}\)
